Exactly as they are supposed to work. Used to take solar eclipse. Worked perfectly.

Bought this and a solar filter and iPhone holder for the 8/21 solar eclipse. Served its purpose very well.

I really liked this filter. I got this filter with the intention of the Solar eclipse that just occured. I am very happy that I got it and will be using again.

Solar charging works better than expected. Infrared could be better.

I was specifically looking for binoculars for the eclipse and somehow got routed to these without realizing that they are NOT solar safe binoculars. My bad for not reading the description well enough. They seem to be pretty decent binoculars, though, even if I have no use for them. Maybe I'll take up bird watching or something...

Finally got to use my new filter. Purchased specifically to take pictures of the solar eclipse. Worked as expected and couldn't be happier. Would definitely buy again.

Got this along with a solar filter for viewing the solar eclipse. Worked fabulously!!!! I also got Orion 7033 Precision Slow-Motion Adapter (https://www.amazon.com/gp/product/B0000XMV86/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1, Eyeskey Universal Phone Spotting Scope Adapter (https://www.amazon.com/gp/product/B01J9F19I8/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1) & Televue Sol-Searcher Solar Finder (https://www.amazon.com/gp/product/B000B785SG/ref=s9_acsd_hps_bw_c_x_2_w). The Solar Finder needed a different screw to connect to the telescope, but it was so much fun to watch and live stream the eclipse!

Great filter but I was looking to use it for last years eclipse and read everything that was on the site about using for the eclipse. Fortunately an astronomer friend kept me from burning out my equipment but showed me other uses for this filter.
