I have these in ask my bathrooms. One set leakedv at handle in the first year of use. I thought that's just an unfortunate event as others were fine till now.  In 8th year  another set started to leak in the same spot. This was in a bathroom that wasn't even used much.  I'm glad it happened now as i was looking for faucets for my new build. I think it's a sign to stay away from Delta as I was leaning towards getting Delta until this happened. I had to replace my kitchen faucet also from Delta this year. If this is what's expected from Delta, i don't have much to say but to spend more money for a higher quality product.
