First time using LS and my experience was terrible. Salesman was not upfront with me and my order took 3 times longer to get.

I have my kitchen cabinets through LS. The quote includes soft closure cabinets but they're not soft closure they just have a little plastic buttons so they don't slam loudly when you close them. They should have soft close your hardware. Also the quote includes installation and we install them ourselves so the quote should never have included installation.

Visited to see some home building products. The staff at LS were extremely helpful. They were great about answering questions we had about windows, siding, shingles.
