My brother and I used the Switch Antigen test to enter the US and the Switch Lamp test to return in the last couple of weeks.

Everything went smoothly - the ability to do the tests at home and get the results document almost instantly was a huge time saver. We did not experiance the QR code sticker issues other have described.

LAMP TEST NOTE: Do not install the batteries till told to do so by the teleheath nurse. The batteries seem to be used to heat the reaction solution and apparenlty dont have much excess power beyond what is needed to run the device the required length of time.Also, the device must be left motionless on a flat surface for the 30 minute processing time, so make sure you are setup for that.

I would certainly use these tests for the next trip (assumiong the testing requirements havnt changed).
