I took several wireless models of the same. I bought the first one about 5 years ago, the quality was then of course much higher. She served for 3-4 years . erased everything that was possible on her)) then the button sunk . after that I bought 3 more of the same ones, I accidentally broke one myself, the buttons on the other two pretty quickly sunk . nevertheless , convenience outweighed the quality . I decided not to overpay for wireless and take a wired one . so far everything is ok
