These drywall anchors work great! I've used both sizes 3/16" and 1/4" and had no problems with either. I always end up using a ton of this around the house as I prefer to do it once and get it right. Cheap dowels with plastic inserts keep coming loose and falling out. So buying those 20 at once seems like a good amount to me. It's also a little cheaper than our local hardware stores. So it's a win-win situation!
