The provided book/instructions were terrible. (see picture) I stared at the page for 10 minutes after laying everything out on my bench.. no luck. no epiphany. FYI: The bars are covered with plastic wrap that I immediately removed which removed all the L/R labels... meaning I had no idea what went where. What eventually helped assemble was to look at the pictures on amazon and compare the pieces I had. Once I had the amazon website up on my big-screen I was able to assemble this in under 15 minutes. Overall the quality is lower than my other 2 bimini tops, BUT this one was much less expensive than those. There are no zippers for side panels or anything fancy. It's a simple, cheap top that keeps the sun off your head. I do appreciate they included rear bars to keep the top away from my outboard when stowed. 4 out of 5, and only for the lack of proper instructions. Totally worth the price otherwise.
