Question: Is the manifier glass ? height adjustible? warranty?
Document: it is as good as its is going to get.. not as adjustable as we thought.. husband uses it, but it only has one height.. the light is kind of irritating actually.. it is ok.. we will use it.
That is the only reason why I only gave it 4 stars instead of 5. That was a little deceiving in the description as far as adjustable height. I think the designers could come up with a simple adjustable sliding action on the pole itself. Then It would be just about perfect! !
I love my new light. I'm getting older and prefer the white light of this lamp and am looking forward to using the pattern clip and magnifying glass in my knitting projects.
I just started doing counted cross stitch and someone told me about Ott lites. Not only does this model provide incredible lighting, but I can clip on my pattern and there is a magnifying glass  to use when needed.
I purchased this lite because I did not have a sufficient source of light above my work station. I can now sew, create scrapbooks, anything which I need extra light for. The magnifying glass and clip were a bonus.
This lamp is a complete waste of money. I bought it precisely so that I could use the magnifier plus lamp for quilting. Although the light itself is somewhat height adjustable, the arms with the magnifier and clip are not. The magnifier is consequently completely useless unless you happen to be very tall or sit on a high chair. I was very disappointed - the rimless magnifier is a wonderful idea, but is completely unusable because of the design.
What they mean by adjustable is the versatility of going from a floor, to table top, to clamp on. This is a wonderful feature and eliminates me having to buy another one for a desk top, but I would have also liked it to be height adjustable on the pole itself. This would come in handy when I am doing hand stitch work in my favorite chair with my husband watching his favorite show on TV. The clamp on feature would work if you had something to clamp on to.
The magnifier is way too high. My husband has one blind eye and uses a magnify glass. I thought this would help him but now I have an ugly lamp in my living room. He cannot use the magnify glass while reading as he would have to put the paper above his head. Do not buy one.
I almost didn't purchase this lamp because of the comments about the magnifying glass being too high. Thanks to S. Johnson from Buffalo for pointing out that the two arms are easily switched to pointing down. That way, it's perfect. When it arrived I thought, "Oh, dear. This is going to be difficult to put together." It was easy and I did it myself.If you are going to do any kind of close work under artificial light, this is excellent.
This lamp looks good in the picture and the description of its function was enticing to buy and use. What I found was it doesn't matter what way it was set up, it was not useful. I still had a shadow on my work area. The magnifying glass was always too far away and wouldn't flex enough to put it in any useful position. The clip and what was on it was in my way. I tried the floor lamp setup and it was too far from my work area.
