Comparison Summary
The GAMMA Momentum 6 Plus MOM6P11 is the most balanced choice for a home stringer who wants six-point mounting and fixed clamps without needing electricity; its floor stand is separate. The Tourna 175-CS offers an especially complete manual tabletop workflow, but its listed 53-pound weight makes it less appealing to move. For a smaller setup, the Klippermate M100 arrives with tools and needs no assembly, while its two-point mount and simpler clamp arrangement suit a more patient pace. Frequent stringers considering powered tensioning should compare the GAMMA Momentum ELS MOELS10 with the Tourna 550-ES: the latter’s electronic controls should not be mistaken for a documented constant-pull function.
Buying Guide
Sizing and Capacity
Here, capacity means whether the mount accommodates your racquet and whether the tensioner covers your intended setting—not how many racquets fit on the machine. Check the exact frame and stringing instructions before choosing a tension range. Published ranges include 9–90 lb for the Momentum 6 Plus and Momentum ST, 20–90 lb for the Klippermate M100, and a listed 15–80 lb for the GT-120. A wider range is useful only if your jobs need it.
Measure the working area as well as the stored footprint. A racquet must rotate with clearance around the handle, and the operator needs room to reach the clamps and gripper. The Tourna 175-CS is listed at 29 by 6.5 inches and 53 lb; those dimensions do not describe all the clearance a mounted racquet needs. The Momentum 6 Plus is listed at 34 lb assembled, while the Momentum ELS is 57 lb. Choose a settled location for heavier tabletop models rather than judging fit by base width alone.
Feature Tradeoffs
Drop weights avoid an outlet and suit a deliberate manual routine. The compact Momentum 2 and Klippermate use two-point mounting; the Momentum 6 Plus and Tourna 175-CS add six-point mounting for buyers who prefer more frame support. Mounting-point count alone does not prove that one finished string job is more accurate: proper adjustment and the racquet’s instructions still matter. Likewise, floating clamps on the Momentum 2 and fixed swivel clamps on the Momentum 6 Plus call for different movements between pulls.
The Tourna 350-CS uses a manual crank lockout tensioner and includes a stand, making it a distinct choice for a dedicated station. The Momentum ST offers a spring winder without electronic controls. Electronic machines differ among themselves: the Momentum ELS lists presets and adjustable pull speeds; Tourna describes the 550-ES as electronic lockout; the GT-E600 listing specifies constant pull. Do not assume that a digital display or finer setting increment changes the type of pull.

Key Specs to Compare
Read the exact model identifier alongside every attractive specification. MOM211 is the second-generation Momentum 2, and MOM6P11 is the second-generation Momentum 6 Plus; earlier Momentum names also appear in GAMMA’s manual archive. For each candidate, compare tension mechanism and stated range, mount type, clamp type, turntable brake, assembled weight, and whether a stand is included. Those details explain more about daily use than a general claim of professional-grade precision.
Check the included kit separately from machine features. Tourna lists pliers, an awl and wrenches with the 175-CS. The Klippermate package includes stringing tools and an introductory string-and-grip package. GAMMA lists basic tools with the Momentum ELS, but its floor stand and cover are separate. Match any seller’s offered bundle to the exact model before assuming accessories shown elsewhere come in the box.
Setup and Handling Considerations
Start with the place you will actually string. A stable flat surface suits the Klippermate; the Tourna 350-CS comes with a height-adjustable stand for someone who wants a designated station. A separately available stand for the Momentum 6 Plus or Momentum ELS should not be counted as part of the machine package. Allow room to rotate a mounted racquet, position clamps, pull tension and keep tools clear of the string path.
During setup, use the instructions for the exact model and adjust the frame supports without treating more clamping pressure as better. The Momentum 2’s marked touchpoints may help a first-time user locate the gripper and drop-weight steps. On a six-point machine, learn its support-adjustment sequence before tensioning your first racquet. A turntable brake can hold orientation during a step, but it does not replace correctly mounting the frame.
Maintenance and Longevity
Clamps, grippers and mounting contacts are the working surfaces worth inspecting as you use a machine. Follow the exact-model instructions for cleaning, adjustment and any calibration procedure rather than applying a generic maintenance schedule. If strings begin slipping or showing marks, check the relevant clamp or gripper setting before increasing pressure indiscriminately. Keep the instructions and included adjustment tools together so a later setup change can be traced to the right model.
Warranty terms deserve the same exact-model check. Tourna lists two years for the 175-CS and 550-ES, while GAMMA lists five-year limited coverage for the Momentum 6 Plus, Momentum ST and Momentum ELS. The Momentum 2’s product listing specifies five-year limited coverage, but GAMMA’s MOM211 product page describes a limited lifetime warranty; confirm the applicable written terms for the machine offered before relying on either description. A warranty is a coverage promise, not evidence that parts will never wear.
Reliability Signals
Useful signals are an identifiable model, matching documentation, stated kit contents and a route to obtain the correct instructions or replacement components. GAMMA’s manual archive distinguishes its original Momentum models from the MOM211, MOM6P11 and MOMST11 generations. Klippermate provides an M100 owner’s manual and parts list. These resources make it easier to check a procedure or identify a part; they do not establish comparative accuracy.
For machines with less exact-model documentation readily available, such as the GT-120 and GT-E600, resolve consequential questions before ordering: which clamps are included, how their controls operate, what the package contains and where to obtain the matching manual. Treat claims about flawless frame protection or perfect tension as design intentions, not guarantees for every racquet and string.
How to Compare Reviews
Match any account you read to both the model and the job being described. Feedback on a GAMMA MOM210 does not automatically describe the MOM211; a comment about a Tourna 350-CS crank does not establish how the electronic 550-ES pulls. Look for the racquet type, string material, requested tension and the writer’s experience level before applying a reported difficulty to your own work.
Descriptions of slipping strings are most useful when they identify the clamp or gripper and how it was adjusted. Comments about setup should distinguish a tabletop machine from a stand-equipped package. For the Momentum ELS, check whether discussion of controls concerns MOELS10 rather than another ELS model. A detailed account of the same configuration and use case is more actionable than a broad claim that a machine is simply fast or accurate.
Common Mistakes
Do not buy by tensioner alone. A powered pull will not make up for clamps or a mounting arrangement that frustrates your routine, and a manual machine can be entirely appropriate for occasional restringing. Do not read a six-point mount as permission to overtighten frame supports. Confirm the racquet’s stringing instructions and the machine’s supported setup before starting.
Other avoidable surprises are assuming the stand is included, confusing shipping weight with assembled weight, and treating all electronic machines as constant-pull models. Check the offered kit against the exact model number—particularly across Momentum generations—and settle any conflicting warranty language in the written terms. If portability matters, take the listed 53 lb of the Tourna 175-CS or 65 lb of the Tourna 550-ES seriously, even though both offer tabletop-style working layouts.
Frequently Asked Questions
Do I need electricity for a tennis stringing machine?
Not for a drop-weight model such as the Momentum 6 Plus, Tourna 175-CS or Klippermate M100, nor for the manual crank Tourna 350-CS. Electronic models such as the Momentum ELS, Tourna 550-ES and GT-E600 need power for their tensioning controls.
Is six-point mounting necessary for a first machine?
No. The Momentum 2 and Klippermate use two-point mounts and suit buyers comfortable with their simpler setups. Choose six-point mounting if you prefer the additional adjustable supports offered by models such as the Momentum 6 Plus or Tourna 175-CS; follow the racquet and machine instructions either way.
Does electronic tensioning always mean constant pull?
No. Tourna identifies the 550-ES as an electronic lockout machine. The GT-E600 listing specifically claims constant pull. Confirm that function for the exact model rather than inferring it from a screen or push-button controls.
Which pick includes a stand?
The Tourna 350-CS listing includes a height-adjustable stand. GAMMA says the floor stands for the Momentum 6 Plus and Momentum ELS are sold separately, so check the offered bundle if a standing workstation is essential.
Final Recommendation
Choose the GAMMA Momentum 6 Plus MOM6P11 if you want the strongest all-around balance of six-point mounting, fixed clamps and electricity-free tensioning for regular home use. If compact, no-assembly setup matters more than that clamp workflow, choose the Klippermate M100 instead. For frequent work that calls for powered controls and presets, consider the GAMMA Momentum ELS MOELS10—and account for its weight and separately sold stand.
