Success. They were cheaper than the originals which I've bought once or twice in the recent past. They work fine. You don't need a red pin to expand them after you put them in. I used a 3/8" drill bit when installing them into the hollow door skin. As for cost, you can get the 100 for $11.99, which is about $12. The Toggler brand was 39 cents apiece when I bought them last year but now they are 21 cents each.
