The quality control the mouse I got had a creaking problem where if I would push on the left side of the shell the mouse would creak. Having said that it did come together nicely and is very sturdy. Im only buying again because Ive seemed to have lost it due to travel which is upsetting but its well worth the money and you definitely get more than you pay for, thanks for making good products at a reasonable price. I wanted headphones that would be safe for my son to use without ruining his hearing, and these work perfectly. Tengo unos auriculares Bluetooth de 24 euros y no tienen ninguna latencia por lo que, el hecho de que unos auriculares de la marca Bose tengan este fallo, me parece un crimen. No work boots or anything particularly heavy, but within a week the over the door hooks began to bend from the weight of the shoes, and then the fabric tore. The construction on the bottom is weak and bent, almost severely injuring me. Have not stressed the battery life, but I have not needed to charge it for several days since I use them only an hour a day for workouts. While it was a bit of a challenge to assemble, once it was done it worked as advertised. The tread hardly looks worn and this is mostly walking on concrete.
