BEWARE! I thought I researched online well enough to know which in ground swimming pool company to place my order. Of course, as you can see, there are several companies involved when ordering from NPW. For starters, I hope you have a lot of friends or family that will help you unload your pool. The freight company they contract doesn't have a large enough lift gate to lower your pool from the truck. Once delivered (ha-ha more like, once you deliver it) I found they send the wrong size wall foam & pump. We ordered the 48" polymer and they send 42" foam. The pump wasn't a two speed as we ordered. And last, they also sent 42" steps which we didn't even notice until assembling the pool & concrete was being delivered! I called Kafko direct (Keep this number 1-888-485-7280), spoke with Tony (ask for him or Scott) and he said I would have my steps in a "couple of days." After threatening to sue him, they were delivered the next afternoon. Speaking of delivery... everything is delivered at different times and took longer than promised. The steps came first, then the pool, the liner, then the slide. Make sure you download the building instructions from Kafko.com because none were included. Just not a pleasant experience to say the least. Definitely shop around! It's been three weeks, and the 42" steps are still sitting in my driveway awating to be picked up as Tony promised. EBAY here I come! lol
