I ordered this for use in my classroom. It worked fine the first day I set it up (Friday). I turned it off over the weekend and restarted it on Monday. It lit up, but the magnets weren't working. After a few minutes, they began to function as normal. However, today (Tuesday), the light still comes on, but the magnets aren't working at all.
Edited: After I posted my review, the Shoppsterz support contacted me in a sincere effort to rectify the situation. They went above and beyond to replace the defective product with a new one, which works perfectly! It's a pleasant surprise to find someone who will stand behind their merchandise and make sure that the buyer is pleased. This company and product are highly recommended.
