Recently returned from a snowmobile trip to Black Hills. I used the Throttle Thumb II the whole time. Rode for over 2 days and kept it on all the time. Fit under the glove and it helped my thumb. I hurt more on one day riding ditches without the product than 2 days riding trails. Will always wear it now. I like that it is fully adjustable for support where I needed.
I didn't read instructions and just put it on with minimal results. Then my club buddy mentioned the instructions. On my next ride everything was great with no thumb issues. I feel like an idiot but I guess most people are like me and think we know everything. It sure pays dividends to follow the manufacturers suggestions. Awesome product!
only used it once so far but wasn't impressed. my thumb still hurt like crazy. was big for my hand, lots wrapped around my wrist. it might work better for someone else, i don't know. i'll try it again tho. it was pretty expensive to just leave it sit.
