Buy two, and install one on each side

Knocking off a star because this slatted panel really is small doesn't feel that sturdy. My kid pinwheels in his sleep so it's not much protection. But I took another reviewer's advice and bought two, and installed one on each side, leaving an opening in the middle - works perfectly. He can still climb in and out easily but he won't fall out while sleeping.

Great product.  I found them a little tricky to install at first, but once I got the knack of it on one side the other was easy.

Perfect for adding a 2nd switch on my garage lights. I needed a double lightswitch cover and the standard covers from the hardware store fit these perfect. The 2nd switch mounts anywhere within remote range and mounts flush on the wall with not cutting required. I would buy this again if needed. Easy to install with little experience.

I bought the two pack, so one less worry for another year! Super easy to install, just twist it in.

Bought this one with the other side and am VERY pleased with both of them.
Excellent product and they bolted up with no problems what so ever.
Fantastic price

Works great, and two can even be stacked one on top of the other in front of one eye. But if you are buying two, one for each eye, then note that it may not work for you because the inter-pupillary distance between your eyes might be slightly different than the distance you will end up having after you mount the two of them on the visor, and the view when looking through the visor lens may be as if your eyes are a little bit crossed.

Two came in the package. Installation was a breeze. With only one installed, the hood was able to be opened and kept in position. With two, the hood flings open super quick. I actually try to make sure it doesn't open too quickly in case it may cause damage to the hood parts. Great replacement!

I bought one about two years ago and screwed it up installing it. It did not last about a year do to my screw up. So I ordered another one and will do it right this time.

Worked fine, trick to get in properly, get another pair of readers while installing to make sure you get in all the way.

Watch the videos first.  This is a really wonderful product for the price. One person can install, but two is better.  Easy to keep clean.
