    This shock works great! I started using Robelle last year with the winterize kit and decided to use the other products offered. This is a great shock to use!! Highly recommend!

    Good value, shipped on time. Works well for my indoor heated pool with swimming jets. Better to buy in bulk. Seems it is often out of stock so buy while you can.
