When I was buying my basis I heard similar things about having to wear it tight to get correct reading. But after wearing it for a few months I've noticed that as long as I'm not running I get the same results, even while sleeping when it's loosened by a hole and it becomes much more comfortable. And tightening it to track my running isn't a huge deal to me. The Bluetooth syncing worked perfectly for me the first week or so but stopped after that now I need to open the app to get it to sync properly over Bluetooth. But, at least for the unit I've gotten I've been extremely satisfied. It's not a perfect device and I would like to be able to access the information myself. When you say Basis B2 do you mean the one with the carbon steel model? I'm fairly certain the B1 is the only model available right.
