Very good, minor improvement could be made Excellent ordering, and delivery of product.Compas is easy to use and can accept various diameters of markers, holds to the board really well.Only improvement is the top of the compas is difficult to lock. It slips if the nut is not really tight. Might want to consider adding some rachets or teeth to hold it in place.

Very useful for a geometry teacher but not stable enough As a geometry teacher, I was so excited about this product. It is definitely helpful for drawing constructions that the whole class can see, but it doesn’t work as well as I had hoped. The device to tighten the arms so that the compass holds its position while you are drawing doesn’t stay tight enough. So, when I’m doing a construction the white board, it often slips. It works fairly well if I’m drawing on a board that is on a table top. Even that, though, does take some finesse.

constructed well, but… This magnetic compass for white boards is sturdy and has all the right features (attachments for white board markers and the tip can either be a suction cup to help it stay in place or a rubber tip for chalkboards). Unfortunately, it is so large (about 17″ long and opens up to make HUGE circles) that it is cumbersome to use. (It could easily be 1/2 or 3/4 its size and still make large enough circles/angles for all students to see.) Also, I cannot seem to get the knob tightened enough to make it…
