I got a Turtle for my commute into SF in the before times, and then last fall got a Turtle 2 because I was starting to ride a lot more with my daughters and figured let's all be safer. I did some research before buying, and the tether seemed to make so much more sense to me than algorithms and subscriptions, not mention no need to send it back to Helite to recharge or check over if it's not showing damage. I mostly don't notice it while riding and I haven't had one inflate yet, but I do feel a lot better while out riding.
