Question: How well do the arms stay in posotion?  I find most of them are always slipping.
Document: It is perfect for the bench. The light in nice and bright and the arms are nice and long. It supports the head extremely well and stays where you adjust it. It shipped fast and was packaged well.
I would had preferred the arms more stable since a move them quite often and the knobs don't seem to keep the position.
They are easy to work with, BUT, back to the lamp,,get one! Even if you have amazing eyes, this lamp is perfect for brightening up tiny things like, ripping threads. I honestly believe every household should have one of these lamps.
I wanted a functional lamp for my work bench and came across this. The quality is better than I expected, the light is bright and the magnifier is a great feature to have on your bench or desk. The lamp clamps easily to the bench/desk and there are several pivot points for every possible angle. Love it!
I LOVE this lamp! I have had one for 20+ years and haul it around the house. The magnification lens combined with the light makes me wish this light was truly portable, I still unplug it, use it in the kitchen, in the sewing/glass/paint room, then, at my desk. I use it for everything and of course, disagree with my husband who should be using it. I got him his very own from Ehobby. They are an honorable, trustworthy, efficient seller.
product seem been use, had toutch up paint and some scratches.on the handle, the lentz have a small dot on it.we except it, we didn want to ship it back and wait again for other one. over all the product looks good quality for the price.
Very ample light source,good magnification and an agile positioning arm make this a fine choice for bench work requiring close in work.
This lamp really helps me see part numbers, and printing in general that is too small for my old eyes to be able to identify. The lamp is real easy to position over your work. The magnification and built in light work great for seeing small print. Just having a light close to my bench, to give extra light, is a great enhancement itself.
The light is bright and clear, the magnifier is incredibly useful, and the base even has an extra outlet .
The clamp is metal and solid and the arm easily adjusts. The magnification is great and the light is nice and bright. Great buy.
