I love this thing, and is a must for any tool box. The length is perfect for those with a larger size hand and provide better leverage for adjusting those turnbuckles.
I use this tool pretty much every time I work on an RC car. A must have for any toolbox - works great for popping ball cups, removing balls from Traxxas rod ends, and adjusting turnbuckles. Works great to separate Traxxas u-joints too. You need this!
Very good tool, I use it at the track almost every time and it has held up great. Would be the perfect tool if the 3mm fit any of my 3mm turnbuckles. The 3mm jaws measure in at 2.96mm with my calipers. All of my 3mm turnbuckles measure pretty much exactly 3mm ranging from 2.98mm to 3.02mm. I have another 3mm wrench that fits great and has never given me any issues, the jaws of that tool measure 3.11mm. I may take a small file to this tool to open it up a bit. 4mm is also a bit tight at 3.96mm, however, that fits all of my 4mm turnbuckles great.
Reviewers consistently praise the tool's length and leverage for adjusting turnbuckles, and two note it is useful for popping ball cups, removing balls from Traxxas rod ends and separating u-joints. One reviewer reports it has held up well with regular track use. The main disagreement concerns fit: one reviewer found the 3mm jaws measure about 2.96mm and would not fit their 3mm turnbuckles, which measure roughly 2.98–3.02mm, while a different 3mm wrench fits. That reviewer also found the 4mm jaws a little tight but workable on their 4mm turnbuckles, and considered filing the jaws open.
