## Description

Product Description ROBERTS First Step Premium Underlayment - 100 sq. ft. Roll - 40" x 30' x 2 mm From the Manufacturer NO-VALUE

Review: Value for the money - Cheaper than the box stores and more for the money. Easy to install, similar quality and thickness to what in-store, easy to cut and fit into desired area, softness dunno about that but it aids with insulating between existing subfloor and the new one being installed.
Review: Great Product for the Price - For the price I can'r really complain. You get a good product for a fraction of what you would pay for a similar product from the big name stores. It seems to do the trick. I installed this upstairs and in the downstairs bedroom. I have two small children and the noise level is reduced. the attached adhesive strip helps also. It's enough to hold it in place but also allows you to move it around if need be. I really don't have any experience with any other underlayment but this seems to do the trick.

### ⭐⭐⭐⭐⭐ Good product at a good price
*by J***. on October 27, 2016*

The contractor that installed the floor seemed to be happy with this material. It gave the floor a nice finished feel walking around. No extra noise with just a hint of cushion. Time will tell on durability and moisture repellent quality.
