Works well
Fits nicely. I have it in the middle over two monitors and it's wide enough to illuminate both. I like that the control is on the top rather than the base, so I don't have to reach under the monitor to turn it on and off.

Really great product. So many attachments, really impressed and will be able to make this work in some interesting ways. Haven't seen recording yet and will update when I do. Happy with it so far!

So far I am enjoying it more than any other BT earpiece I have had before. I can not tell it from a new one, so it was worth the savings.

Must be connected to internet
The camera is a good deal in as of itself. But one little problem. Not just this one but with mostAnd that is if you loose your internet you are out. Yes unless you are near where your camera is. And the internet goes out so does itWell sort of. There is a way to reset your cameras and internet without being there.A little device that gets hooked up between you power and router.Try to find the right one for you and hook it up.What surprises me it that many of the companies that supply the cameras don’t supply the auto restart. When the power is restored. Just wish I could get one from the camera supplier when purchasing the equipment

Worth the money.
Very well made camera. Needed a camera due to people breaking in cars on my block. First night that I put it up we caught the guy clear as day. Worth the money.

Small and powerful
I needed some multi-media speakers for my new PC build downstairs. I already have some Focal Alpha's in my home studio upstairs, so I didn't really want something sub-standard for my PC setup, even though it's not my main computer for doing music. These small monitors had good reviews, so I though I would give them a go. Well, all I can say is, I'm very impressed. Plenty of volume for a small desktop setup, but more importantly, the quality of sound is much better than I imagined. So much so, I actually spend more time recording guitar on my PC downstairs than I do in my actual home studio. Bear in my mind, I am no expert, and I don't have tons of expensive gear, etc.. But, if it feels right, I just go with it..

Great performance, reasonable price!
Mechanically it could be smoother, but it does perform excellent polarization filtering!My camera auto focuses very well with THIS filter!(Previously I bought a AGFA brand filter that was HORRIBLE!)

Q
Could both 100 by 100 filter and 100 by 150mm filters work with this mount system?
A
Yes, of course 
Q
Will this frame fit onto a 100 mm objective lens on a celestron 25 x 100 binoculars? actual od is about 105 mm. the intended use is full moon view.
A
The od size is 100mm, the set comes with multiple different sizes to fit many different lens. You do not need long exposures for good moon detail, 500 sec at f8 works good on full moon 
Q
Can i use this on a canon d80 100 mm macro ef lens ? it says 67 mm on the lens cap but i don't see the exact answer. thank you
A
67mm should also be stenciled on the front edge of the lens somewhere. If so, then you should be good to go. It should be on the lens because a lens cap can be lost or broken. 
Q
How can I know my lens mount/camera mount?
A
  1. You could consult us or search the mount information online
  2. You could find the mount information on your instruction book when purchase the lens/camera
  3. The mount information may be showed on front of the lens, side of the lens, rear of the lens or on the lens cap, usually it is a 2 or 3 letter code such as: CN, FD, OM, MAF, NK, N/AIS or F/AX
 
Q
Can i use this on a 95 mm lens without an adapter ring?
A
It can't not be fixed well with the lens without the adapter ring. you should buy another adapter ring of 95mm size if you want to make this square filter fixed on the lens.
