They do have a trade up program from other speed trainers (US only but you would be okay)I saw this on chasing scratch Instagram. The Bluetooth on it seems like a really nice feature. I think they have a trade up program, I might do that if I end up getting a stack
I just noticed the bundle discount they are currently offering is slightly more than you get if someone gives you their referral code ($50 off) and they do not stack either. So they've removed that benefit for existing users for now at least. I wonder how long they will keep that going.
EDIT oh you mean trade up on LM. Yeah, it's $47, you're far better off trying to sell it to a friend or on ebay for like $100 or so
