We have a large kidney shaped pool, which is currently empty, without alot of surrounding area. I decided to have professionals install in for me to ensure it was placed down correctly... I didn't want a bunch of unnecessary holes in my concrete...lol. I'm not great with the whole "measure twice, cut once rule"...lol. Surprisingly, with me having a oddly shaped pool, the cover did a great job at covering the entire pool and then some.Regarding the ability to walk across it, well the jury is still out on that. The very next day, I found my 90 lb dog on the cover, near the shallow end. The cover bowed so I had to get on my belly and reach out to grab her and help her off the cover (it was slippery for her). Thankfully, it didn't tear or anything like that even though she was trying to get her footing by attempting to dig her nails in the cover, but was unsuccessful. So, I'm not sure how well it will hold someone like my husband, who is about 215lbs. But, overall I feel it will do the job with keeping my family protected.As far as keeping debris and rain out, the cover seems to be excellent with that. It has rained a couple of times and there were small puddles of rain that collected on the top, but evaporated by the next day or so.It took the professionals about 3-4 hours to complete, as they had to repurchase some type of diamond drill bits to properly make holes in the concrete; for the one's that came with the cover broke, or something like that.I'll write an update 6-12 months from now to report if it's still going strong. I've only had it installed for about 4 weeks, so we shall see!(Posted photos)
