PULOX vs Acer E2B / Optoma ZD201

I've gained the Optoma HD300X me a while ago and was looking for a set of matching, halfway affordable shutter glasses. This proved to some research, as not so easy out: In the DLP Link technology, the projector sends after each image a flash of color, which is recognized by the glasses via a photo sensor and ensures that the spectacles the eye changes. However, the glasses have to filter the color flash itself, otherwise the 3D image is distorted. The Optoma example uses a red flash of color, and when I look at the 3D image without glasses, one sees in a row a distinct reddish tinge.
Optoma's own DLP Link glasses, the ZD201 (identical to the Acer E2B), filters the color flash. But many no-name glasses apparently not doing this what would tarnish the 3D enjoyment but significantly. The PULOX forms here fortunately an exception.

I ordered one each PULOX and Acer E2B glasses with the projector. First, I would note that the PULOX glasses, although it is only half as expensive, much better endowed brings: You get a storage bag, a microfiber cloth and a USB charging cable (Standard Micro-USB, for example can also be used for mobile phones ). With Acer you only get the glasses, which is not supplied unlike PULOX glasses with a battery, but by means of button cell power. Both have advantages and disadvantages, the button cell at least interchangeable.
Furthermore, the glasses of PULOX are a good deal larger than the Acer, what I feel comfortable. Otherwise, both glasses can wear well and have a similar weight. The PULOX can also easily use by eyeglass wearers. The glasses are PULOX tinted greenish-yellow and have at viewing eg an LCD monitor polarisationsfilternde properties (but are certainly not used as a polarizing filter glasses). The glasses of the Acer other hand just seems a little darker. I would therefore have expected that Acer should provide a slightly better image.
In practical test I however it can not find anything. With two glasses the result for me was practically identical, I also can not tell the color cast in the PULOX. Both filter glasses to sync Rotblitz the Optoma perfectly what can be seen in particular in black areas immediately. If there are differences, they were for my (admittedly untrained) eye at least not recognizable.

Conclusion: Half-price obtained here a DLP shutter glasses, which is the well-known competitors from Acer and Optoma in image quality equal and in the equipment and the size of the glasses even slightly superior. In my view, therefore, full marks.
