Bests & Worsts Reviews from Amazon

I spent a lot of time reviewing similar products as I have purchased similar products over the last 15 or so years, past experience was varied with other products - some were terrible, others were less than adequate - problems with battery life, low output lamps (older type incandescent bulbs), problems with poor adjustability, weight, build quality, LENS choices and/or lens quality - I even experimented with separate lights and magnifying glasses to try and find the right combination. These are as close to perfect as it comes - first for the price my expectations were not high - but the build quality is great (even though my first pair broke - although I think if I would have READ the adjustment/Lens changing instructions more carefully I may have avoided this mishap. Either way, they replaced the broken product IMMEDIATELY, before I even filed a request because this company proactively reaches out after purchase to check up on customer satisfaction and to answer any questions - WOW - the product is extremely comfortable, lightweight yet rugged enough to stay adjusted without moving around, others made my head and face sweat - these do not , LENS are fantastic, they are optically clear, do not distort, can be infinitely adjusted (focal length and angle) & the combination of magnification thickness is good for most jobs, the built in light is very bright, doesn't get hot & is also adjustable, good combination of flood and spot so it provides the right amount of WHITE light where you need it, so far the battery life has been excellent. The combination of using either the headband (great if you are using for extended period or if you need to work lying on your back or side (they do not fall off or move), band is adjustable or you can easily switch to standard over the ear eyeglass type for quick jobs or when you need to take glasses on/off while working. Storage case for LENS is top notch as is included polishing cloth, even the shipping box can be used to store the glasses to keep them safe and clean between jobs as it has a molded interior to prevent glasses from banging around and box is not too large and is heavy duty for long life. Instructions are very detailed with pictures and actually well written (in proper / correct English so it is CLEAR). Again, follow directions on how to adjust focal length (requires a good quality small head Phillips screwdriver to make this adjustment for best clarity - I noticed that this does not have to be moved often once it is set correctly for the most common lenses - for me I need to adjust this only when I use the STRONGEST magnifying Lens - the 1-4 Lens can use the same adjustment (this may be different for you - depends on your eyesight), either way, its a simple quick adjustment, but this piece performs several functions and is very well made but you need to be careful because it is an important 3 way adjustable piece (LENS Holder) Nosepiece is adjustable & more comfortable than my prescription glasses, all the parts that come in contact with your skin have a comfortable non-slip rubber like padding (no slick plastic that would slide around if you sweat, touching your skin). These little comfort and functional features you usually don't find in a product in this price range - it is ergonomically designed/engineered - a lot of thought went into form/function, comfort - still can't believe how light they are and how well they work and how easy they are to adjust it seems they thought of everything. I paid 4 x or more for other glasses that don't come close to these, even separate headlights that I bought don't come close to proving the right amount of light exactly where I need it. You cannot combine lens - only one at a time, you can where your glasses under these (plenty of room for my head and glasses anyway, Lens can be lifted out of the way without removing headset if need be - but because of focal length, adjustability and light weight, you can forget you have them on, and with the lens sticking out from your forehead several inches, I have turned my head while I had it stuck behind an equipment rack and either knocked something off the shelf or clipped the Lens on side of rack and pulled them out of the holder, fell to hard floor and bounced around, LENS did not break (they are strong and not soft plastic like the ones made 10 or so years ago) they are a hard (H5 degrees) and do not easily scratch under normal working conditions. Can use soapy warm water to remove greasy, grimy finger prints - comes with HQ eyeglass cleaning cloth. Changing Ear clips to band is a pretty stiff HD clip, takes a little finger/thumb strength to push button down to release lock (good thing). I like using the band just to keep them in place when I am behind equipment close to wall and they are so comfortable, I sometimes forget they are even there (almost took my wife's eye out with the LENS edge when I kissed her goodbye when she left for work!!) Have not found (so far) anything negative - I am really impressed with these I don't write too many reviews but I think these are great especially since I work on electronics that require a lot of close detail work and my eyes are getting worse on close up work (I can read a street sign 1/2 block away!!!) - these allow me to see close up so I can work again without have a 1/2 pound of lights and 3 different pairs of glasses on my head!! LOL Not to Mention - the GREAT VALUE - the empty box, and storage container with the 5 LENS is worth the purchase price never mind the fantastic fully adjustable, brightly lit magnifying Glasses - seriously these are a no brainer for what they do - I hope they last as long as I think they will. I would buy them again even if I only got a year of weekly use out of them. Because of the adjustments and lightweight - they certainly are not indestructible - not recommended for heavy duty work where they would be exposed to heavy tools or extreme temps, dirt, chemicals, grease, etc.. these are perfect for electronics, jewelry, watch repair, controlled environment, they are IMHO part of a fine work toolkit, not designed for a heavy duty machine shop environment set of glasses, wouldn't last a day. Keep original box to store them in - they should last a while if properly cared for - and no EXPENSIVE BUTTON BATTERIES to worry about - uses 3 x AAA, common long lasting batteries.
