This board could have been a perfect board for my son, but the stain does not come out from white board and the white board plastic (the materiel) started getting wrinkles. It is difficult to get any thing out of white board for adults, kids cannot remove it at all with the eraser or a cloth.

We use this fan in our office space, clipped on to a window ledge. The clip is sturdy and holds well. Battery life is good. USB charger cord means we can plug it right into the computer monitor when it needs to be recharged.

I have purchased three packs of these thermometers. I rely on these for several of my tanks, including quarantine tanks for sick fish. I find that they are extremely accurate and easy to read. Great for the price and will continue to purchase these digital ones over the old-fashioned glass thermometers.
