I've had it for a couple of years. The LEDs aren't hot and the whole assembly is quite sturdy but it is still easy to move the magnifier into position. It can wiggle back and forth for a few seconds when you adjust it but it settles down quickly.
Your lamp looks similar to the Busy Bee lamp but it is not exactly the same. Mine has a handle to use when moving the lamp and it also has a mounting bracket. You can drill a hole in a block of wood as a mount but the clamp is very handy.
In short, they look similar but are not the same product although the list prices are about the same when you take the differences in the dollars into account. Which is better, I don't know.
Hope this helps.
