Class DLP 3D shutter glasses at a low price

I have recently bought a 3D projector (BenQ W703D) and was at the same time also looking after ordinary 3D glasses.
The previous reviews then led me to ordering the spectacles of Vidimensio because the other branded products were too expensive and the cheaper deals did not come to me because of the corresponding rating in question.

It was also important to me that power for glasses is necessary. A pair of glasses with battery and USB charging cable I did not want to, you must always remember to recharge in time and when the battery is faulty times, the whole spectacle is no longer usable.
Quite different in these glasses, they are operated with commercially available button cells (CR2032), which may be obtained for very little money and made to last. So I have not ever recharge, it's enough a few batteries on reserve to have.

What should make the glasses, it makes very good.
She works with my beamer together perfectly, the image through the lens is absolutely uniform, no color distortion or brightness differences.

Small drawback: For eyeglass wearers this model unfortunately does not sit perfectly and the inner edge of the glasses disturb something, another model of Vidimensio what I have is that when it comes to the inner edge better.
