I bought this product for my son. He uses it to add resistance to his everyday training. We would on occasion race each other up a hill near our house and normally I would win but I am now ashamed to say he blew me away on the last one!

Works well and solved my purpose. Quantity is also good for the price. I am using it to wash my car once week and it has given satisfactory results.

You should know this is my first time writing a review - good or bad - for anything in my life. I often find people who review products on a regular basis to just be incredibly inept and bratty, so if you think that also, this is the review you should read.
