The treadmill works as expected. I had an issue with the remote at first, but after sending the seller a message, they promptly replaced it.
There are no physical buttons on the treadmill. I don't want to think what would happen if the remote stopped working or I lost it.
I wish there was a way to PAUSE by using the remote.
The iOS app leaves a lot to be desired. Mainly, there's a lot of unnecessary bloated parts to it (it has an 'ad' screen sometimes that you have to wait before you get into the app). If the phone is in landscape mode, you can't access some of the controls to pause or start the treadmill.
But so far the treadmill seems to suit my needs.
