Always. ### 1/5 — Don’t work *2024-03-15* Couldn’t open the account msg server failed ### 2/5 — Sensor Connectivity Issues *2020-09-18, version 1.2.366* The Bluetooth connection is an issue even with the app’s update. This needs to get fixed, so far this product is useless. I already have a timing ball, but, I purchased this unit for the game part. Since that’s not functional, I feel like I wasted my money. I’ve even purchased a new sensor for $115, please fix this issue! If it’s a sensor issue and I wasted another $115, I will not be a loyal Nexersys customer anymore. ### 5/5 — FIX THE BLUETOOTH *2017-10-29, version 1.2.366* This will get 5 stars when I can consistently do full workouts without the Bluetooth disconnecting. The update was supposed to fix that, but I still have to frequently stop mid-workout to reconnect the Bluetooth. At the very least, at least let us try to reconnect while it's paused. Don't make us quit the workout to try to fix your errors in technology! Sometimes, the Bluetooth just flat out won't work, and it's not because of the batteries. That's like having a game system where the controller "sometimes works." ### 5/5 — Fun, challenging, and engaging ! *2017-10-10, version 1.2.366* This is a great app to use with the crossbody trainer system. It has different levels of work out intensity, plus many variations of routines. Don’t let a double end bag make you think your not getting a great workout. Keeps me coming back and the kids like the interaction, and it keeps them motivated to exercise. This is a must have app if you have the crosstrainer , but even without the sensor hooked up, it makes a great double end bag work out. ## Frequently asked questions about Cross Body Trainer ### What is Cross Body Trainer?
