Does not focus at high resolution

Does not focus at high resolution. Lenses are not clear even in good light, image is foggy. Individual eye focus is limited compared to other binoculars. Even at a low price the binocular will not satisfy it's intended purpose.

Bought it for the magnification but at high magnification it is hard to focus and hold still enough.  Somewhat bulky.  Use my little pocket 30x Sony more but the Sony does not have a view port where this one does.

No side focus, magnification is blurry at closer ranges because of this. Buy a scope with side focus, parallax adjustment, a bit more money spent will be well worth it.

We could never get a crisply focused image through my high end binoculars and IPhone 7.  Tried multiple times and had my son try too.  Disappointing.  will give it away to Goodwill because it is worthless, unfortunately, to us.  Buyer beware!

This monitor has some great features, the height adjustment is great, you can rotate the monitor vertically without remounting.  It is a very good design.
The problem is Acer does not allow the monitor to display higher resolutions than 1920x1080 for HDMI or DVI.  HDMI can display 1920X1200 and HDMI can display 2560X1440.
I have a couple viewsonic 4k monitors that allow the maximum.
Unfortunately, I am returning this monitor.  It really has a nice design but is too expensive for such low resolution.

Autofocus does not work at higher zoom. Have to switch to manual focus. Havent used the macro mode much. Otherwise the results are OK.

Had to return mine as no matter what, I could not get it to focus clearly. Included software was pointless and severely outdated. In order for software to run it uses Legacy CPL which is a slow way to communicate with the camera. Find another that is more modern and can use standard drivers.

Returned it. It would not focus when the image is retangular or straight. If the image was kept at an angle is was clear and focused. Costumer service was good. Gave 3 start because of costumer service. Didn't get to try and enjoy the product, returned it the next day after it got delivered. Maybe I got the defective product.

I may have received a defective product. But has all the features AO focus 9x magnification.  Will work for bench shooting but i found the eye relief is left with much to be desired.  I did find the sweet spot and picture was clear out to 100 yards but hard to sight targets unsupported

I'm really sorry, but I had to return this item ad ask for a refund.  I could not get it to focus.  I tried everything, my husband and my son both tried and none of us could get it to focus so I contacted Amazon and returned it.

Like another reviewer mentioned before, this microscope has many nice features within it. But at the higher resolution I also had a blurring issue and in occasions the image would freeze; even after tweaking with the software. I bought this for troubleshooting and repair of electronic component boards, but sadly it doesn't meet the standards for doing such task. Frustrated at the end, I sent it back through Amazon for a refund and will be looking for a better microscope.

Wide lens and fisheye work fine but macro won't focus. The image is blurry and I can't get it to work. It's probably my phone, it's fine I got it mainly for the wide angle lens.

It may just be me, but I am not getting fine resolution from it. It does not produce the distance resolution I expected. Will give you a subsequent or follow-up if things change.

The image is blurry, but works pretty well. Too bad they don't have the ability to adjust the focus depending on where you're shining the image.

Could not get the image to focus at all, no matter how hard I tried. Changed the distance, the settings, pitch black room - but when top half was in focus, the bottom half was not... and I did adjust the tilt as well. Nothing seemed to help. Also was not as bright as expected per the description.
Returned without problem tho

Im not a pro photographer, but I like good quality lens at good prices. Unfortunately this isn't one, the lens had trouble focusing trough the viewfinder, and corner were super soft even at f11.

I do over 1000 Webex sessions a year and have run with Logitech for years. Used at a high level the C910 and C920 series. Purchased the 930E, and it will not SAVE focus or tilt adjustments. Therefore, each new session or video, I have to waste time to readjust the view screen. I contacted LT support, they said there was no way to fix it. I have asked for a refund and going back to the older webcams. Very disappointing.
