My white boards has exceeded expectations on more than one occasion. The custom printed pictures I created on magnetic white boards were fantastic, clear, and the staff was great on following up any additional requests that i had after the Drawings were sent out for proofing. Great job! Highly recommend for business needs! Also shipping after proofing shipping was extremely Fast!

Such a great product

I want to thank you for such a great product. I have installed several whiteboards in our offices over the last couple of years. Now we are expanding and need to order more. Never really happy with the quality of those we have. Got one of yours to test the quality and we all are quite impressed. We will be ordering 4 more of the Great White 4 x 6 version. Good job!

Thanks for all you do.
Merchant Response:Thank you so much for the kind review, Randall!

I am very impressed with our new whiteboard! This is not your average whiteboard, it is far superior. It is high quality, sturdy, flat (not flimsy, warped, or damaged like the ones I've previously purchased on Amazon and eBay). The hanging mechanism is extremely sturdy. I am pretty certain it would survive an earthquake or hurricane--it is not going anywhere. It is well worth the investment. The customer service was also outstanding!
Merchant Response:Thank you so much for the kind review! We're so glad the Great White Magnetic Whiteboard impressed you.
quality is exceptional very sturdy no offensive glare/sheen looks great easy and secure hanging mechanism clear instructions magnets hold nicely none

Good service and quality

Received two 4x8 magnetic marker boards on time and with delivery updates from the truck carrier. Packaging was good enough to protect the boards and easy to open and discard. Teacher feedback regarding the boards was very positive - no ghosting and no glare from the boards. Magnet works great! Thanks.

I picked up this board because I could get it in the exact size I needed and because of some of the reviews for less expensive boards that said they tend to flex because they're thin. I knew that would be annoying because I would be using it often when teaching classes. So I ordered this one. It came quickly, with easy instructions for installing it, and shortly I had it hanging on our conference room wall. I love the heavy duty look and feel of this board. If you need one that will be constantly used, this is the board for you. ONE SIDE NOTE: I noticed after using it that there is a pinhead sized chip that grabs marker dust and never gets cleaned. I called MyWhiteBoards and the guy told me the surface is actually porcelain. So I'm going to pick up a little white Testor's paint and fill it in. It's certainly not a reason to return the product or to reduce my satisfaction with it, but the guy said I should mention it.
