For a while I thought the sensor was great but over time I realized it was more of a burden and provided little to no extra value to my tunings. Tuning every string to the freeze frame with the sensor I received occasional complaints from clients (one was a Grammy award winning household name) and had to redo tunings by tuning unisons aurally to make them happy. I believed at the time these clients were ignorant, but after time it set in that I might be wrong. Most improvements while using the sensor I eventually realized resulted from changing my tuning techniques and switching software. I think in my case I wanted it to work and was blinded for a while. The sensor was a time burden (especially on uprights) and once I took a break from it after 100 tunings I realized I didn't need it and my life was better without it. I haven't touched it in several months now. 

I've tuned many many times without the sensor in noisy environments. And if it's really that noisy I'd rather just come back another time or ask if people can be quiet while I tune rather than fiddling with the sensor. If not, I can always pop out a tuning one way another in a very noisy environment. 

I was going to sell the sensor but realized it would be unethical to do so based on my experience with it.

This is a truthful and honest review and I hope it doesn't get flagged.
