I purchased the Dapper Snapper for my two and a half year old grandson.  His Mom and I love them.  They work great for pants with belt loops.  I had to purchase clips for non-loop pants off of another site.  This is a great product I wish I'd have thought of it.  Belts are often to heavy and bulky around the middle for toddlers.  They also cause issues for using the potty. The Dapper snappers work great.  I highly recommned them.
