Customer Reviews

600 sq. ft. Value Roll of Black Jack Pro 2-in-1 Laminate Underlayment is rated 1.5 out of 5 by 2.
Rated 1 out of 5 by from It "looks" like it should be a good product.... you see the black and think it looks like serious... It "looks" like it should be a good product.... you see the black and think it looks like serious tough stuff. In reality, this stuff is garbage. I've used less expensive stuff (blue) that was waaaay better quality. This tears easily, squishes easily and doesn't pop back (like if you leave a hammer on it overnight, that shape is indented there in the morning and takes a couple days to pop back. I bought this online (sight unseen) because it was a big roll and that seemed easier than buying small rolls and piecing stuff together on my longs runs. That part was convenient, but I wouldn't buy this again. It wouldn't surprise me if the weight of the flooring were squishing it down flat and rendering it useless...I don't even want to know, considering what we spent on the flooring and how long it took to install it all. Go to the store and TOUCH the different underlayments before you buy. I'd rate this about a 2 out of 10 for quality.

Rated 2 out of 5 by from you get what you pay for It is cheap, and barely survives installation. Dont think of it as a moisture barrier, as it tears when you look at it. I should have spent more on a better product
