If it was, say, a $10 filter set I would probably give it 3 stars. But given that I paid $30 for it, I'm not happy at all. First, that beautiful pure green color you see in the product image is 100% bs. The green I got wasn't even close, but an evil looking, almost puke green (brown green). That's not acceptable here. Second, one of the filters I received had a thread snapped right out of the box and although it screws on it never tightens properly. It's almost $4 for a filter, it's unbearable. Another thing is that the colors are rather weak. The only thing I would call really good color depth is blue. Others are lightly colored and do almost nothing to filter out unwanted spectra. (Confirmed by my spectroscope, which only showed an average 10-20% color reduction in unwanted colors.) A perfect example of this is the red filter, which although it looks reddish when viewed through or through light, actually makes it pretty clear. it's more of a reddish orange. Finally, the threads don't seem to clean up very well after trimming, as I've already had two thread binds where I could barely get them off to the point where I'm surprised I didn't break them. Overall, for the price, the product is of low quality in color and apparently in quality as my problem showed me.
