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.

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

Warranty
I must say recently had to test the warranty on an older red dot from cylee .and they are great to deal with had a red dot that was 2 years old but still under warranty. Got in touch with cylee and within a week and a half had a replacement optic .so guys buy with confidence this company is for real and stand behind there product I will continue to buy as they are affordable and a great product.

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

Not working without even using it.
Stopped working properly without ever really using it. It’s been sitting in my safe since I bought it just over a year ago and now it does not work right. The buttons don’t adjust the brightness and I can’t turn it off. It’s literally been in the safe on a rifle that I haven’t even shot yet. Very disappointed in this. It’s been just over a year and I doubt that it is still covered under warranty so I guess I’m stuck with it.

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 for the price
I bought this just to put on a range gun because of the features and the price.After putting about 500/600 rounds through it I have to say it’s a fantastic optic for what you pay.I have many much more expensive optics but I would not hesitate to use this on anything that I carry.I like it so much I bought a second one just to have on standby in case I need an extra. If you’re looking for a good dot at a great price give this a shot.
