I installed a baby-loc about 2 years ago because we had a little girl. Its a good product. None of the temporary fencing gives me much confidence... But as long as it is used as a last resort to constant supervision, then it is great. That is the intention.
It isn't cheap. Im lucky to have a family member in the business that got me the product at cost. So I just had to have it installed. The gate is a nice option but you do not need it.
Ill post a picture of how it looks around the pool. Our gate is in the middle so not in this pic. As long as there is a lot of tension, these are pretty tough to get through. Ive gone inside, locked the gate, and prodded my 3 year old to push, pull, lift, etc to get in. There is no way she could.
I only took it down 1 time in 2 years and that was when we had a hurricane. I figured I should bring it in so it wouldn't blow away

It came down very quickly and went up very quickly also. I have removed 6' sections to bring furniture and things like that in.
But still, I wouldnt trust this even the slightest bit on its own... All in all, its a bunch of mesh that uses tension to keep kids out. Constant supervision is KEY!!! I know this usually goes without saying but I dont sleep any better at night knowing I have this fence. It really is the last piece of safety in case somehow your kid sneaks by unnoticed.
