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.
