Tension but what tension?
This device is so non specific, very much depends on the person using it plus so much can vary. It does not give a racquet tension in terms of string tension but a reading of tension in relation to the device which is different for every person using the device. Awareness is needed to know whether it is testing a main or a cross string. There is no obvious limiter to when to stop a tension check so it is possible to go to the maximum of the device. User strength varies as does different types of strings. A good stringer will know instinctively or by sound how a racquet is tensioned. A nice idea but difficult to execute.

The device works as expected. The measurement uses Strength Tension Index (STI). This is different from LBs, if you want to know the current tension, there is a formula you can use. To calculate the tension in LBs you need to know the racket min and max racket tension. With those numbers you then can use the following formula. Tension (lbs) = Minimum Tension (lbs) + [(Maximum Tension (lbs) - Minimum Tension (lbs)) x (STI ÷ 100)] For example I got fresh strings today, the STI is a little before 38, to calculate the tension, I checked online my racket has a min 48lbs max 57lbs tension. With all that we plug it into the formula Tension (lbs) = 48 + [(57 - 48) x (38 ÷ 100)] = 48 + [9 x 0.38] = 48 + 3.42 = 51.42 lbs

I just had my racquet restrung with Synthetic Gut at 52# by a professional stringer. I used this gauge on the new stringbed and it indicated very close to 52#. if you insert it into a square of strings that are close together, it's easier to get an accurate read. After reading all the 1 star reviews, I don't understand how they all had so much trouble. This gauge is not a professional instrument nor is it represented as one. When I turned the dial, I suppose I could have believed the tension to be anything between 50-52# - I knew mine was at 52#. But that is still pretty good for a $20 gauge. This will be a great tool to monitor the tension and replace the strings when they get below 45#.
