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

Excellent Red Dot for My Smith & Wesson 9mm Compact – Clear, Bright, and Reliable!
I mounted the Cyelee Red Dot Sight on my Smith & Wesson 9mm Compact, and I’m extremely impressed with its performance. The brightness settings are spot on, allowing for a crisp, clear dot in both low light and bright sunlight. The glass clarity is excellent, with no distortion, making target acquisition fast and accurate. One of my favorite features is the shake awake function – the sight automatically powers on with movement and powers off when idle, which is perfect for everyday carry and saves battery life. The auto on/off feature works flawlessly, so I don’t have to worry about manually switching it on before using it. Build quality is solid, and it feels durable without adding much weight to the pistol. After several range sessions, it has held zero perfectly and shows no sign of loosening up. For the price, this is a fantastic red dot that performs like higher-end models. Highly recommend for anyone looking to upgrade their pistol with a reliable, clear, and bright red dot sight.

Good Value
The product works as expected and holds zero well. There are two caveats with this specific model. 1. The Docter fit is not precise and requires modification for a four post installation. 2. The X1 does not come with a cover.

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.

Great sight for the price
I have this on my ar at a 45 and used the same one on my handgun hold 0 even on the ar. The shake awake works great and is always ready to go.

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...

Great Job Cyelee! Amazing Love Above HoloSun!
Short and sweet, I own and have purchased many optics, everything from Holosun, Trijicon, Mecanik, Vortex, Etc. They are all great but expensive. I have a Prodigy DS-5 Inch that came with a Hex Dragonfly. After blowing out (3) optics I reached my limit, even though It is under warranty and can be replaced. I have a friend who said. Look bro, you need to check out this Company Cyelee. They are 1/3 of the price, Zero is amazing and you can really beat them up and the reliability is just there! So I bougth (2) different models! Let me say UNBELIEVABLE. Not just UNBELIEVABLE but spectacular. I had an issue with the screws, Tyler from customer service responded in seconds. Sent me a screw pack the next day. I installed the unit and have now put 2000 rounds through it. Never lost Zero one time! I also purchased a wolf 01 from Cyelee!!! Great job, Superior Product! They have my business going forward! Powerful son of a gun for the price! Rob

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.
