Monte, our installer, was awesome. Did a great job. Very professional. Bathroom looks great. He even did a few extras like hanging the LED mirror, etc. We just have to do a few finishing touches like paint, get a backsplash for the vanity that we purchased and replace the small light fixture above the mirror.
Yes, I would definitely recommend YHIC.
