In general, excellent product, easy to use, good quality. The quality of the light produced is very good, maybe a CRI90 rating. I wasn't sure how well the spring system would work, but it worked great. The ceiling I installed has a popcorn style finish. The only downside is they don't dim as low as I would like (with a Lutron Caseta dimmer switch) but as I use them in the kitchen for general lighting this isn't a problem. I would consider using them again for applications where ultra low dimming is not important.
