 Focal lenth off, May 07, 2017
By Mark

I bought the DA-4, 2x Mag with a focal length of 10". I like the product but when I measure the focal length it's only 7". I put on my glasses and that doesn't change (I'm near sighted). I also bought the loop and tried it with the 2x mag and focal length was 3". I expected that distance with the loop. But the product clearly says 2 power with a 10" focal length and that simple is not true for me. That means more neck strain than was anticipated. If the lens itself could be held back from your eyes that would increase the distance from your eyes to the object in focus. The head gear is not adjustable in that way and seemingly would provide much more adjustability if it were. The lens are held in with small screws and nuts requiring some fiddling with a wrench when it could have been produced with a wing nut or knurled nut that doesn't req a wrench. This means the loop and changing lens is more of an issue. Not a show stopper but the focal length should be understood as inaccurate.

 Great aid, February 10, 2017

This is my first magnifier....been too proud.....wished I hadn't been. These are wonderful. The only thing they need is a light....there are light kits on amazon, but I have no idea how well they work out. If you're working on a bench that's really lit well, you won't need a light. But I use these all over the place because my eyes are so bad. Focused field of view is about ten inches like they say. You step up again in magnification and your focus field is even less. In my search for these, that's s fairly standard caveat. They are reasonably comfortable...even forget I have them on sometimes. I think for the money, these are boss. Made in the US(wow), real people to deal with if you have any problems.

 Not the usual Donegan quality . I was shocked. TWICE ! Finally satisfied with newest replacement., September 29, 2016
By RICKVOO

I have several of the Donegan OptiVISOR’s in various magnifications so I know what to expect in regards to quality. I never had a problem, until now. I bought the DA-7 magnification for very close-up work and when it arrived I was shocked to find the glass lenses literally falling out of the plastic frame.
So, no problem, I’ll simply snap the lenses into place and write this off as a poor assembly job by the manufacturer. After numerous attempts to get the lenses to snap into place I gave up as I was afraid of breaking the plastic frame. It appears the glass lenses are just not contoured properly and I presume the factory assembler reached the same conclusion.
As is my usual approach, I first tried to contact the manufacturer via their customer service e-mail. I try to do this before writing a product review whenever possible. I got no response so here is my review. I will now take this through the very good Amazon product return/exchange channels. I had hoped to avoid that and simply get a new lens assembly from the manufacturer. Now they’ll have to replace the whole visor. I do prefer the glass lenses compared to the molded optical plastic. They are more scratch resistant IMO.
UPDATE: Okay, Amazon shipped another right away before the first one was returned. I couldn't believe my eyes. The replacement has lenses that also are not positioned well. This can't be right! How can a product with uneven lens positioning be appropriate for precision binocular vision? If I'm wrong I wish the Donegan folks would educate me but they don't respond.
UPDATE: After writing a letter to the Donegan president I did finally get a response. They shipped me a new lens plate and asked that I return the questionable one, which I did. The newest plate is much better with the two glass lenses aligned well. So, I’m improving my review to 4 stars because I believe the quality of Donegan products is usually good.

Probably the BEST., September 18, 2016
By Mark H.

This Donegan OptiVISOR costs more than the various "knock-offs," but as an experienced user of many headband magnifiers, I must say that the extra cost is WORTH IT ! Better and more thoughtful construction, Good lenses also. Foe something like this product, please RESIST the temptation to buy cheap. Get the Donegan... and if you need to be cheap, be cheap on something else :-)

The real thing - excellent optics., September 08, 2016
By not_bob

I use these for watchmaking and soldering of small SMA components. I love them. The optics are great. The first time I purchase one, I was stupid and purchased the highest magnification. #5 (this one) is much better for most applications. The optics are real ground glass and they hold up to cleaning.
The head piece is slightly uncomfortable. A redesign here would be advised. I end up with a red patch on my forehead when I wear these for too long. I'm sure that there is a way to modify these to make them more comfortable, but I haven't gotten around to it yet.
Overall, these are a good value and a great tool. Donegan has been doing this for 50 years I'd guess. There are cheap chinese knockoffs, but in my world these are worth a few extra bucks for a quality, genuine product.

Finally, I got the correct replacement. I had ..., August 25, 2016
By James Walker

Finally, I got the correct replacement. I had lost my original Opti-visor and could not remember who had made it. After purchasing a cheap imitation, and being less than enthused with its performance, I ordered this. It took a little bit of searching to make sure I got a suitable replacement. I guessed at the focal length I needed and hit it perfectly. The visor doesn't loosen up when moving it up and down into viewing position, and is very well made.
