Can use Alexa on normal mode but I also have it on my phone and other devices! But several months of use reveal problems. The earbuds held a charge very well and the case kept them charged when not in use with no issueCase: the case is very compact. For someone like me and at my age, Im not used to paying more for slippers than sneakers, but the $10 Wally World slippers wouldnt have lasted this long. This cord seems to be super durable and I don?t foresee the wires coming out. Way too small and narrow. The detail, seperation and imaging are very impressive. It just happened to be an item that offered extra fast delivery. the bottoms started to detach from the actual boot such as these other reviews have said and the worst part is that they started to smell like feet after a few times wearing them! My pinky toe wants to escape out from below the strap.
