I love this thing! Out of box, it was already charged and I attached it to my Vortex binoculars and took photos. It was very easy to turn the ring to secure it on, and to get it focused. I love its little screen, which makes adjustment much easier.

The only real downside is the app is a bit clunky and could use a better UI. I definitely look forward to putting it on my compound microscope next. Highly recommend!

I have only used the camera a few times, the images are great, adjusting the visible and thermal alignment is easy. I have to remove the phone case (Otterbox) in order to connect.

Decent enough piece of equipment but the ring that indicates how many stops of light are being blocked is out of alignment. At ND 400 (the maximum), you can still obtain more light blockage by pushing the ring further before it starts to go clear again. In other words the maximum measurement (and, therefore, all other measurements) are not correctly indicated.

We just love this binoculars!

Very satisfied. Fits perfectly with my Canon 50mm 1.8. The precise alignment with my Pentax Q. surface and the smooth operation are first class. Everything snaps into place and movement is effortless. My only observation is that the LOCK <-------> OPEN locking mechanism could be a little tighter to be sure the adapter doesn't detach from the lens. This is especially a problem when using larger and longer lenses with this adapter. If this change can be made, I can't think of any other manufacturer that can match this level of quality. A great and fantastic purchase.

Out of the box GREAT, very lite and very sturdy. Love it..

Out of the box this filter is well made, threads on and adjusts smoothly. The optics are quality and I was pleased with the photos. I did experience some vignetting when pushed to the limits, but that might have been caused with me having the UV filter still attached and like I said that was at the very extreme end of the filter position. Very impressed with the filter and it's quality. The photos were F8, ISO 100 and 1/160,1/25 and 1.6 sec. Would buy again.

I love this so much. Out camping I bring along a big Jackery battery pack and several smaller battery packs for a few things. It took a few hours but this charged up every single thing from nothing to full. It weighs nearly nothing for the power it can provide. I'm really happy this is in my camping/ emergency kit.
