good product and service
Would Recommendproduct was good but my local store didn't have a machine to blow it in and had to go to store in decatur al and get the machine and bought the other 30 bags i used .The store in decatur had the best customer service of any lowes i have ever been in . Lowes needs send all asociates to the decatur al store for their training.

Great value, not difficult to do.
Would Not RecommendMy wife fed the blower and I was in the attic spraying an additional layer of insulation. Never did it before but it was easy to do. I recommend eye protection as well as earplugs. It wasn’t that noisy but some of that fiberglass can get into your ears and that’s not good. A lot of insulation for the cost, I think it was a great value

If your blowing insulation, this works great.

Attic Insulation
Would RecommendI wish the calculators for the blow in insulation were more accurate. Online calculator said I needed 9 bags for my area to achieve 12" of cover for at least R30. It took 15 bags which I fortunately guessed I should get and could return leftover bags. It took every but of 15.

Product was good. Worked as expected. Rental process was very confusing and staff were not familiar with how to do it. Return was worse. Took a wry long time to figure out how to return equipment in Lowe’s system
