the BEST doctor cut optic
P.S- AUTO ON/OFF WILL NOT WORK WITH PROVIDED BATTERY!!when your red dot shows up in the mail, first thing you do is DO NOT INSTALL the battery that comes with it/UNINSTALL the battery that is in it when it arrives. it is a junk battery and will make your red dot not function proper. go buy a good Energizer/Duracell Lithium 2032 and any issues you make have noticed will vanish. (notably the auto off not working will be fixed)as far as a good Docter Cut optic, the pickings are slim. the Vortex Venom is a fine dot, Trijicon is the king and these Cyelee are (imo) the best bang for your buck and it isnt even close. these punch way above their weight class.The dif light modes are great and shine well in sunlight. loud, solid clicks while zeroing and sighting it in.9 month review: i changed the battery the day i got the dot which was 9 months ago and the battery is still working just fine. i would advise a new battery every year but they really tuned these to save battery life. this budget dot is so great and cyelee has been super responsive in our very limited communication.if you are in need of a Docter Cut, look no further because unless you want to get the Trijicon, this is the option for you

Perfect Fit for My PSA 5.7 Rock – Super Clear and Reliable
Mounted this on my PSA 5.7 Rock and couldn't be happier with the setup. The Cyelee red dot feels solid right out of the box, and the larger lens really makes a difference—super clear sight picture with no distortion around the edges.The Shake Awake feature is a game changer. I love not having to worry about switching it on or off—it’s always ready when I need it, and battery life has been great so far. Zeroing was quick and easy, and it’s held true after several range trips and a couple of light drops (oops).It looks great on the Rock and functions even better. For the price, I honestly wasn’t expecting this level of quality, but it’s exceeded expectations. Would definitely recommend for anyone running a 5.7 or looking for a reliable red dot with premium features.

Working good so far!
The auto on off works good. Turns on with any real movement but not so sensitive it turns on while the table it's on, gets leaned on. It was probably close to on target out of the box. The build quality seems great. It was misting out when I was shooting but probably put 200 rounds through it. No problems. It's bright enough for a pretty bright day. I'll update when I get it zeroed better. Seems great for the money. In fact it seems like it's almost better than the vortex venom ergonomically. Venom are the only longstanding competitor for the Dr cut optics. Reviews for venom don't sound great and they cost 3x the money

Bang for the buck
Overall, I'm really liking this optic. The glass is nice and clear, the dot is crisp, and it locks up solid with the Dokter cut mounted to a Vortex Spitfire 5x prism. The only thing that takes away from the optic is the elevation and windage adjustments. The cut on the knobs is difficult to get a good seat with the tool and the lack of any real tactile or audible feedback made the zero process far more difficult at the outset. Maybe cut the notch a little deeper and better feedback for the adjustments? With that said, during the zero process and after I got the dot where it needed to be, the grouping was beautiful.This is my first Cyelee and I am impressed with the performance and value. After testing this out, I am far more inclined to check out some of your other offerings for other projects.

Great budget option that competes with the high priced competitors.
I originally bought this to put my my TX22 handgun. Being 40 plus, I suffer from presbyopia, making my near vision bad. I bought this because I want optics on all of my non-revolver handguns, and specifically so I could train with my TX22 for if I should ever need to use my XDM OSP Elite for self defense. At the time I bought it, I had a Vortex Viper on my XDM. Upon arrival I was blown away at the build quality. Quality steel and glass are used on this red dot. When you hold it in your hand, you can tell it is a quality product. Because the Vortex products are not shake awake, I decided based on the build quality I would put it on my XDM instead and put the Vortex on the TX22. I took it to the range this weekend and cycled 100 rounds through it. It held zero the entire time.This red dot is affordable, accurate, and reliable.Even better, the owner seems to stand behind his product, sending me a personal email that if I should have a problem to contact him directly.Great product, great value.

Not reliable
Sight mounted properly and zeroed just fine out of the box, until I used it once on a canik tp9sfx at the range and after 3 mags the sight was no longer holding zero and was unable to adjust to zero again as the mechanism had broke and wasn't able to adjust it enough to sight in the red dot after that unfortunately. Otherwise great red dot for the price. Super disappointed to say the least...

CYELEE is the Next Holosun and even better. A+++
Keep your eyes on Cyelee! This company is Moving Up Fast and before you know it their prices will skyrocket.This Red Dot is definitely Made for Law Enforcement (Duty Ready). I replaced my Trijicon RMR With this one. It’s Waterproof, Shock resistant, MOA is bright and the lens is very clear. Battery Life is amazing.It doesn’t have self adjusting brightness (which is Not a big deal). the shake/wake feature works fine (after 10 to 15 minutes it will shut down).I zero my Red Dots at 15 yards, it is Super Accurate and holds the zero indefinitely (after 300 rounds).
