Review on TOGGLER Toggle Hollow Door Polypropylene Fastener by Harry Love

I use these on a hollow door to attach a full door rubber shelf for my kitchen pantry. I've been using them for 3 months now and I have about 30lbs of static load on them and they are still tight and won't move a bit. They are very easy to install, it took about 5 minutes. For the price they are unbeatable. Update: 3 months with a 30lb static load and it still shows no signs of shearing. Update 2: 5 months and up to 35 pounds.
