Product review (4 stars): Hard to put on but they work great
I had read some of the other reviews and I thought I needed to grind down two of the plastic tabs so this would fit. But I didn't have to do that. It turns out that they just fit really snug. I tried to put them in when I first got them but didn't do it right so I thought I needed to grind down the two posts. Well, once I put them aside I forgot about them for at least a month.

I finally decided to try again and while I did have to press really hard to get them in they fit perfectly and work just fine. If they weren't so hard to put in I would have given 5 stars but at least I didn't have to grind anything off to make them fit.
