I like that it isn’t silicone like my last one which just felt almost sticky, this has a glossy smooth finish and is easier to wipe down and keep clean. My kit came with login details for the TRX App which has more workouts than I can possibly need. People complain of the case, but I find it small profiles and very pocket able. I got these for my son who is 8. The only issue is the tools. This case is awesome not only does it go hand in hand with the matching watch strap you can buy but has stood the test of time. says "4-Year Battery Life". This dress fit PERFECTLY! Ok so its not the best its came to me bent and had it exchanged for a new 1 which also came a tiny bit bent but was usable it hold your kicks but wish they had a way to secure the sneaker since they could easily slide off from either side. I also included a comparison of the Mi 4 vs Mi 3 displays.
