I received a refund notice also without an explanation. I suppose I will just wait until they are in full production and buy one when they are not in fubar mode.   

They are about 10 cents a round where I buy them.

Aguila Colibri should do the job for you. You can also go with the super Colibri but they have powder in them and are louder. The Colibri are just primer and sound just like an airgun.
