Query: cant slice jello

I bought this as a gift for my wife. It held up for one maybe two times before we started hearing grinding noises when the blade would stop during slicing. Now after maybe 6 to 8 uses the blade stops as soon as you start to slice anything. It has plastic geared teeth which is the problem. I strongly recommend NOT buying this product.
