I leave it just because no one has bluetooth. what was my choice I bought 3 different trackpads to try and this was the worst. he stutters, he is lethargic, sometimes he just stops for a second and slows down until he crawls. If I stop briefly, it works fine for a while. I definitely wouldn't play with that. BUT, when I plugged it in, instead of using Bluetooth, it worked pretty much the way a cheap laptop trackpad usually works. just an average windows trackpad. Bad enough to make you respect Apple trackpads; good enough not to travel with a mouse in your pocket. If I didn't need Bluetooth (!) I would send it back. [along with a HORRIBLE brand of jellycomb which I returned.] BTW the best I tried was https://www.amazon.com/gp/product/B07VBLLDXR/ I'll be back to tell you how long the internal battery will last. that worries me the most.
