Great product for going over bathroom tile and put laminate or Vynal flooring over it
Worked for what I needed it for. You can spend $20 more as of listing at Home Depot or Lowes and get the same stuff.This worked excellent for my Masterbathroom.Definitely, recommend it was placed over existing tile and works great.

Nice for the price
Works great specially the money you save on it yes itâs a lil had to keep in place but I rather deal with that or use painter tape to put together than pay for expensive I got all mine here for my whole house saved like $1500

Thin packaging, good foam
I am not using this for its intended purpose, rather for resist material when wet felting.The packaging is not ideal, it comes wrapped in thin plastic that is only taped securely at the top. Mine ripped during shipment and left a couple tears in the first layer on the roll. The tape for the product label also ripped the foam when I tried to peel it off. This is easy to work around and only some was damaged.Overall its a very thin foam and will work well for my intended purpose, and it’s a good value for the amount (at least compared to other foam sheet products).I wish the plastic it came packaged in was a thicker plastic, or taped in more areas.

Secret shopper –
Very very thin
If you buy it to save money comparing it to Home Depotâs kind-donât, you have to double this up sometimes triple for transitions so in the end you need to use twice as much and itâs actually more expensive.

Affordable underlayment.
Itâs exactly as described. For the money, its worth buying.

I use this underlay to create my resists for wet felting projects. Light enough to layout the wool and roll and it’s thin enough to allow for the water to work through it/around it so that I can complete projects before removing the resist. Who knew? 🙂

Although this is on the cheaper side for what it is, for a few extra dollars you can get something A million times better. This was infuriating to work with but not impossible. It was way thinner than I had hoped and tore whenever I tried to slide the lament into place. Even some other options in a similar price range will come with tape to adhere it to the floor so it will not slide and stay in place but this DOES NOT. No adhesive and unless you tape it yourself this will move every which way and again cause issues in your projects. Buy and beware, it can be useful but for similar pricing there are some better options.
