I have been using a Janty classic for a few weeks now, I ran out of carts and I finally found a store located near my that sells njoy products only, I bought a pack of njoy carts thinking they would be compatible with my Janty, they are not. Is there any way to modify the cart, such as pulling out the wool and inserting it in the Janty cart with a pair of tweezers? This is probably a big hassle, but I really don't want to go back to analogs waiting for my Janty carts to come in, any suggestions would be helpful...
