My uro/surgeon is not impressed with the pump, but as a no-nerves-spared guy (me), what else would he do than let me have it with insurance? It does not do damage, and even the slightest positive is more than zero.
After all was considered, it cost me about $100 co=pay/shipping, which is what a good non-rx version would cost.
Whether the doc is all on board or not should not factor in. The pump is FDA approved.
