Query: Well constructed and engineered

Positives1. Thick canvas material.2. Thick hi-vis windows.3. Heavy duty zippers.4. The ratchet system for tightening the top to the frame works well.5. Nice shade of tan.6. About as close as you can get to a custom top.Negatives1. The velcro strips did not adhere to the frame. I had to use an adhesive to stick the velcro to the cart. This could be because of the cold weather and cold metal and plastic.2. On the club car there is an area towards the bottom of the windshield that is not covered, which lets in cold air.
