I have one of the ramps too but am embarrassed to say it is in the box in my garage instead of in the pool. My pool cleaner is very sensitive and seems to hang up on anything at all extra in the pool. I even have to pull my ladder up when we are not in the pool so the Polaris does not get stuck on it.
When my youngest son was little I had an extra fence around just the pool so he could not fall in as he ran everywhere. I didn't let him out by himself either but there was no slowing him down, so we figured the extra fence was needed.
Wish I still had it up now with my grandson coming over & the pups everyday. It just made one more safety net between them and the water.
