As a builder who loves DIY stuff this sensor set is a game changer for my cycling routine I use it with my phone and other devices to track every pedal stroke and speed which helps me improve my rides and shave off time its so handy for comparing my performance over weeks Ive been using it for a couple months now and its become a must have for my daily commutes and weekend rides with the kids the waterproof feature is a lifesaver in Kolkata's rains and the long battery life means I dont have to worry about it dying mid ride highly recommend for anyone who wants accurate data without the hassle tips make sure to mount it securely to avoid any slippage and pair it before your first ride for best results overall extremely satisfied and it feels like a solid investment for my fitness goals
- Pros: Extremely easy to set up just slapped it on my bike and it worked right away no fuss at all the battery lasts forever like I havent changed it in ages and it connects to all my gadgets without any issues rain or shine it keeps going strong very reliable for daily rides
- Cons: Could be wrong but sometimes the data feels a tiny bit off maybe needs a better calibration or something nothing major but for a perfectionist like me it could be annoying
