Great quality camera! And super fast shipping as well!

If you're not used to wearing an ear-bud style headset, you may experience mild discomfort at first but, for me, I found it to be comfortable. Remember: this is for one ear - not two.I liked that I was able to simultaneously setup my laptop and phone with the device.The device worked very well; I was able to make and take calls right away, listen to music, and be heard clearly.This is especially handy off hours for me as I am recovering from a surgery and can't always hold up or prop up my phone to my ear so I leave it in my carrying pouch.

まあ使えています。ただ、ＬＥＤの光量に依存するから離れるとダメみたい

Used it right out of the box and it was amazing! Great picture and easy to use.

I have been using this filter primarily to get rid of glare in my webcam setup so my requirements may not be as stringent as for more classical applications. Compared to a Nikon filter I have (of a different size, for a different lens), the polarization effect is a bit lower on the Tiffen, and it also lets through more light. Contrary to some comparisons I've seen online though, the Tiffen for me produces a warmer picture than the Nikon.
