Query: Great while it works

I've owned this product for about two years. It has seen no winters and has generally been used about once a day during summer months. I have 100' of medium grade hose installed.Initially the unit worked very well - it fully retracted all the hose and I made sure never to let it bind up at the end. This summer the unit started slipping and pulsing. After disassembling it, I noticed that not only was the large plastic (very poorly made) sun gear cracked, but the unit leaks internally. It is now completely useless.For $ 85.00 I thought I would get a few years out of it. All the good reviews in here are in for a shock when their units start failing (which they will).If your a fan of nature, you might be impressed by this units ability to safely house a number of different interesting insects.
