I've had it for about a year, and it's permanently in my bag without worrying about whether I have any files with me.
I back up my laptop much more often since it takes very little time.
Also, I can take the most essential things with me everywhere, which is invaluable.
I haven't had any problems of any kind and I highly recommend it. I use it on a MacBook Pro M1.
Also for me, while the X10 existed, I believe the difference in speed isn't worth the difference in price... personal opinion...
Important: get a waterproof/hard case to keep your mind at ease...
