Not worth the money. Filters 2, 4 and 10X make the images quite coarse. Very limited focal plane and the optics are quite blurry. The 1X magnetic filter is the best I can reasonably use. Then the quality drops. I'm sure you could get anything out of a 2X filter with a tripod and under ideal conditions, but I doubt 4 or 10 will ever be useful. I'll add photos later. If I had known this beforehand, I would have just bought a 1X filter and saved some money.
