The only good thing I can say about this mouse is that I love the button layout, and I really hope we see more start adopting similar layouts so I can then throw this one in the trash and get something else. These issues could be resolved by adding some hard structure/frame to this mount that would hold the phone more firmly and reduce shaking. I purchased a red color from Amazon. I walked around in them for maybe 20min. On top of that, you can also use it in a directly wired mode and forgo the Blu Tooth entirely. I ordered a size bigger for my daughter and they were still small. Compré 2 de estos, después de aproximadamente 30 dias de uso extensivo no me han dado ningun problema. I was breaking out the teflon spray on q-tip inside of 2 weeks. They are comfortable to wear and fold into a compact carrying case (sold separately). This is such a weird device, I thought something was missing when I opened it first 😁it is cool, snug fit and means you can constantly charge and pick the speaker up whenever you want without the need to unplug all the time (cause plug is in the cradle)
