Very pleased
Color: Black, Size: 8' Wide x 30" Tall
This works great, and I find it to be very effective at soundproofing. The hinge is good quality, and it rolls up easily. It is slightly on the heavier side, but that is to be expected considering its larger size. The materials used to make it are top quality, and it will last a long time.

Massive problems with timely shipping and delivery!!!
Color: Grey, Size: 8' Wide x 6'6" Tall
I have purchased three panels at $1300 plus each. The first two came very late, in one shipment; the third in a separate shipment. I have yet to receive the third, despite being present when shipping has twice said the business was closed. The first two were delivered almost a week late after numerous discussions (over four hours with Amazon support in online chat and phone) specifying there is NO WAY the business was closed as it is open 24/7. CAUTION. Further, the video is misleading. The panels are 70 pounds. A 5’2 athletic woman will most likely need assistance to balance and stabilize the panels. The magnetic buttons work IF you can get the panels aligned, which must be a two-person job for a petite individual due to the panel’s 8 foot height. Check reviews thoroughly for the stability feet which can be purchased separately; the recommended sets are plastic and not sturdy. Overall: BEWARE of shipping and delivery drama. Do not expect this product timely. Ensure two people are available if you are not tall. Recommend consideration for a different acoustic panel system. I will most likely be cancelling the panel I have not yet received. The expense is not worth the numerous issues. Good luck.
