No longer supported

This is no longer working… I have been unable to login the App for the past 6 months. I contacted support and got an error message on one of the email addresses (mailbox full) and no answer on the other ones for the past 2 months. I tried to reset my password, create a new account, same error at login (unknown error). Trouble is without login the device on the racquet does not connect to the App and so it is completely useless. Except as a dampener but it is not a very good one and bulky and expensive as such!

Very inaccurate

New firmware has not solved how inaccurate this QLIPP device is in recognizing types of shots. It also does very little to dampen string vibration so it fails on its two stated missions. Go with a Zepp 2 or wait for the new Courtmatics device coming out in February.
