Cyelee CAT0(CAT Upgraded) Micro Red Dot Sight, 3MOA Reflex Sight for RMS/RMSc/407k/507k Footprint with Motion Deactivated Standby(Similiar to Shake Awake)

*I’ve only got 50 rounds of 9mm on this.This comes packaged tightly in a neat box like most Red Dots will. This model in particular comes with s ton of different screws to fit you slide cut. Im not sure why they are needed, but I was able to find a set that matched my GX4 perfectly. They are pre-loaded with blue loctite as well. It fit the rmsc cut perfectly and looks great.It took me a few rounds to get the elevation dialed in. That is on my and my like of ability to not jerk the trigger. The windage was super easy and had that on target in a breeze. Through the first 50 rounds it held 0.Someone said the brightness wasnt good in daylight, but I disagree. I have two vortex red dots, and this model was just as bright as the others. I prefer a 3 moa reticle, but it is smaller. I used this outside on a full sun day after a light snow (1” of snow.). I could see it fine.Im going to use this more before determining if it is my new favorite model or not. But the quality and price seem great for what I am looking to do. I cant find any reason to grade it down at this point.**Edit** I have had a chance to check on the shake awake function. I let it rest on the dresser, I returned 30 minutes later and without picking it up looked down the lens, and it had turned off. I picked it up and held it, by time I was in the sight it was on and operational. The plus is shake awake works. Im guessing, but who knows- that wearing it in a belt holster and walking would be enough to turn it on? Im not sure and dont know how to test that.

Excellent value red dot! It has shake to wake, great battery life, easily replaceable battery, easy brightness adjustment, and easy fine tuning for dot placement. Additionally, it came with a TON of screws to fit all kinds of optics arrangements. The pre-applied loctite on the screws did not hold for me, but some regular loctite fixed that up no problem after it came loose the first time around. Using it with a Taurus TX22 compact and it fits great, and the size is great for the gun too. I got a coupon code from a youtuber to get 20% off, which made it a no-brainer purchase. I'd get it again, highly recommended.

I wanted to wait until I had put it through some testing. Holds up well. A lot of rounds and still holding zero

Good inexpensive red dot. Has held zero on my 43x. Decent quality, functions as noted and is a good compact fit.

Good deal. Works well so far.

Very nice size, this is my first RMSc footprint optic and I am amazed by the size compared to RMR. Window is still a very decent size and dot is crisp and easy to pick up. (Remember to practice your draw and be sure your aim meets your eye) Dot gets plenty bright and plenty dim so it will function in all lighting conditions, buttons are very tactile. I got my initial zero using a laser bore sight in my pistol and then made my adjustments firing 5 round groups on paper. Hits dead on and was very easy. Auto on and auto off works perfectly and is a staple feature in every red dot I own. This makes my now 6th or 7th Cyelee optic I own and I am amazed by the quality every time, especially for the money.I do wish the windage and elevation screws had a more tactile "click" to them but they do provide some feel to the adjustments. My personal note would be to swap the inlcuded button batteries for a Duracell or Energizer branded ones. As the ones they include don't have the longest life span. Still pretty awesome that they even include a battery, let alone two!!

from day one it had problems first it did not want to go into sleep mode had to take the battery out fixed that. then i got a range day fired well over 500 rounds and had my torque wrench with me and it did not hold 0 at all. this is on a Taurus tx22 as i shot it the adjustment knobs moved on there own maybe if it had clicks in it help it hold it in place .

I bought this to replace my 407k on my Hellcat. I like that I don't need an adapter plate and the dot is much smaller, which is better for me.I previously bought a wolf0 and put it on a range toy and have been so impressed by it that I decided to give the cat0 a chance. I will have to put it through the ringer to make sure I can trust my life to it, but the wolf0 has held up no issues, which gives me hope for the cat0.The box says it has a larger window than both the 407k and the wolf0, but the wolf0 window seems bigger when they're side by side. It is bigger than the 407k. The shake awake feature did work on mine. The box says 7-8 minutes, but when I tested it... it shut off around 5 minutes.Update: One thing I will say is that the Wolf0 (RMR) isn't as bright and it's hard to see outside in daylight, but this Cat0 (RMSc) gets much brighter and after 6 months and probably 600 rounds or so, it is EDC approved.
