I bought few of these panels few weeks ago and used them to sound proof my vocal/guitar boot and mixing room. I got rid of bouncing sound and feedback. Also found out that the tone coming out of my monitors is much more precise and clear. For me there is no cons. This product works great and does its job. I'm just about to order few more for my main studio room. It can easily stand next to some similar absorbers from much more expensive price range. I recommend it for everyone who would like to save some $£ and still get good results.
For a 1metre Sq of Acoustic Foam of this quality this is great value. Easily mounted and with careful positioning it will definitely work. It has the perfect depth in the pyramid matrix design and the charcoal grey colour is nice and neutral and will blend in with any colour scheme. With Acoustic Treatment at this price and quality there is no real excuse not to have your studio sounding good. It would be nice to see it packaged better though than simply rolled up and just taped together in a roll. It deserves better packaging to make it look more professional when you buy it and for company's own reputation too.
