They look good, but do not turn all the way around without a serious bind. No way am I going to be able to do anything with them except for mock-ups until I get better quality units.

So far this is worth every penny. For interfacing with the rasPi, I found it to work much better using the NOT A and B connection, where the lines are normally high, and pulses are falling edges. Wrote a quick app using libgpio to verify operation, and so far seems very accurate, not missing any pulses, and provides clean square wave outputs (ie no denouncing required).

I have had four of these units fail out of the box. The quality control is terrible. All of the failures were different. Hard to turn, missing B pulses, overheats and stops working. missing A pulses.Terrible product.

Feels very solid. Connected it to 5v. Very clean pulses. Great product.

Just opened the box and performed a quick test. I like the clicking detent. The other review I see didn’t like it. But, I would expect to have the click. Only complaint is a few blemishes in the aluminum. But, not a huge concern. I will update this review if I find any problems.
