Slendertone Connect US Customer Insights

1. I have had to work with customer support repeatedly, very frustrating!! The few times I have been able to get it to work it is pretty good, but I am tired of reinstalling software, re-pairing my device, etc for a brand new device.Just like other people's problems...Won't connect anymore... I can control it from device but not knowing the level setting.

2. Repro: start app, start program, connect to belt, run session all the way through without closing app, wait for belt to turn off, go to tone menu, observe "disconnected" screen, turn on belt by holding center button for 3 seconds, observe "disconnected" screen never connects, wait 30 seconds, still nothing.Buggy. Ive had to reconnect 3 times in 2 weeks for "errors".

3. Unpaired the device but it wont forget device from phone... even though every other device can be forgotten...hmm. uninstalled/reinstalled app but still no pairing.. device will shut down before it can pair.

4. The only other change is I turned off my watch's Bluetooth.App has to be restarted between every session or it won't connect to the belt the next time.

5. It will recognize device but never pair.Doesnt keep track of my sessions.

6. Very disappointed.If you don't care about having to install and uninstall several times to get it to work and don't care about wanting to throw the controller across the room after a dozen or more uninstall and install sessions go right ahead and use it.

7. Yet if I open the app and turn on the device it doesn't connect.

8. I have reinstalled, ensured I had the most update app version, I cleared the cache and memory, restarted my device several times now and I still get the same error.

9. Waste of money to buy app one, I followed instructions I keep it fully charged change pads regularly but probably 2 out of 5 time each use it saves sessions that's being generous.

10. Fortunately (with effort) the control on the belt will function the control without the app... But then you cant track what level/setting.

11. I get to the step of it identifying the last four of the serial number and confirming, but after that it says it is unable to connect.
