Works well. Easy the assemble.
I bought 5 of these and they are working great. My 11 year old grandson built one the other day and it turned out good after we discovered he had switched one 8550 with an 8050. It is nice when a mistake like this doesn't cause anything to burn up. After putting things where they belonged it worked well. We mounted it on a 6 volt battery box with a power switch and he had a nice little project to show at school.
seems to be OK quality for the money
well made circuit board and value for money, built two in an evening and they work fine
Seems to be good quality. Haven't tryed yet
