The glass works great, the sharpness is excellent, it just can't be put under the protective film, at least my Kowax 730 helmet has grips for attachment in front of this film

Very good magnification, a clear visual image despite the "plastic". Since the disc is on the inside, I hope it will last a long time, but if necessary, the second disc is included as a replacement. Absolutely recommended.

Product is used for magnification under welding helmet. Need reading glasses. Welding glass with my vision strength of 2 diopters is ideal for this. Sweat like young lord again.

For a long time I worked with reading glasses under my welding helmet, but the constant putting on and taking off of the glasses was somehow annoying. This is much more practical with the magnifying lenses in the helmet. It is important that the lenses are close to the eyes, so adjust the helmet so that the lens is as close to the eyes as possible. Otherwise, there will be slight distortions in vision if the distance to the eye is greater.

I never come to weld without them, they are just 100% in order..

Is good as described

I am very satisfied with the product

Good workmanship, fits exactly, good visibility. And very fast delivery

Excellent for me when welding with it and fits very well with the hood, I recommend it to all welders who have difficulty seeing up close.
