Desk lamp (LED)
I use this lamp in my work shop. The ability to adjust the intensity is one of the primary reasons I purchased this product. I am very pleased with it. I gave five stars for the sleep mode I do know it work, for I had tried it, I doubt I will need the sleep mode. It's there, so it's a plus.

Great product
It charges fast and lasts all day. I work in a call center type job and I use it for 4 hours then charge it at lunch for 30 min. Then use it for another 4 hrs. Today I had a meeting after work so I did as above then charged it for about an hour before my meeting and it lasted for another 4 hours best product I have found.

Amazing for the price
I would buy this 100X's again. For the price, this set is awesome!! I used the helmet mount on a 5 hour motorcycle ride and the wrist strap while shark diving and canyoning. i used the pole many times as well. Just those 3 items made it well worth the money.

Q
Will the autofocus function of the lens be affected after using the adapter ring?
A
The adapter ring itself does not contain any electronic components, so it will not affect the autofocus function of the lens. 
Q
Hello, who is the software for update the ring adapter ?!
A
hello,currently the product does not need to be upgraded, so there is no firmware.only when compatibility problems are found do you need to upgrade the firmware. 
Q
When used with telephoto lens, the adapter ring may be loose
A
That may be caused by the fact that the lens weight is much bigger than camera, If used your telephoto lens with our adapter ring, we suggest to use with a lens bracket and better to shoot on a tripod to increase its stability. 
Q
Too loose/there is gap between lens and adapter ring
A
  1. If there is ever any more than a slight amount of rotational play, you may want to try tightening the lens mount adapter so it will hold the lens tighter to the mount. There are 3 flanges in the middle of the adapter (what the lens locks onto) that are split open slightly, this gap is what gives the tension that holds the lens tight to the body. Over time and with use these gaps decrease in size, no longer pulling the lens tight to the adapter, which allows the lens to move inside the mount more than it should.
  2. To tighten the fit, get a slim metal object (a #1.5 or #2.0 small flat eyeglass screwdriver is ideal) and insert it into the slit to open it up just a little bit (see images below, make sure to do it to all 3 evenly). The more you open the gap, the tighter the lens will be to the adapter; too much and the lens will have a hard time mounting so make sure to do it just a little bit at a time to all 3 flanges evenly, it doesn’t take much at all to get a tight fit.Note: please do not use too much strength, or the shrapnel will be damaged.
 
Q
If i use this on a nikon lens that has an aperture control ring, what would i set the control ring on the adapter to? thanks!
A
