Otter Shake Awake 3 MOA Micro Red Dot Sight, fit RMS-c/507K Footprint Pistol, 1x21mm Mini Open Reflex Optics Compact Scope, Shockproof, Lightweight

So far so good. Initial inspection shows sight of excellent quality. I bought this red dot specifically because I saw several reviews giving it very high marks. And one review the guy BTLS out of it and it had no affect on it. I own over a dozen red dots and RMR's varying in cost from $30 to $249 so I have some experience with red dots. I currently have a Ameriglo on my PDP/C and love it but it has to large of a foot print for the gun I Put this red dot on.I really appreciate the fact the sight comes with every possible screw you will ever need to mount it PLUS one or two additional screw for every gun you might mount this on as well as a spare screw for the battery cover.It comes with very well written easy to understand directions on how to both mount the sight and sight it in.The red dot is very bright and will work under any lighting conditions you will ever encounter for the brightest mid day sun on a cloudless day to very dimly lit indoors or outdoors and even in the barest of minimal light. Buttons for adjusting brightness are firm and seam very well made. Adjustment screws also seam very well made and not at all mushy when adjusted. This sight punches WAAAAAAY above its cost so far. I have 500 rounds of ammo I plan on firing my next off day and will update my review with my results. Can not believe this 50,000 hour shake-awake sight only cost less than $147 TMD. If it performs well on the range as so many YT reviews claim it does this will undoubtedly be one of the best values in a red dot currently available. WE shall see.

I purchased the Otter red dot last August, and I haven't regretted the choice at all.Installation on my pistol was simple, and all needed screws were provided in the box by Zulisy. The sight has been rock steady and held zero through several thousand rounds of practice firing. I like the battery access on the side, so I don't need to unmount the sight to change a battery. (Not that I'll need to do that for a few more years!)Mounted on my Hellcat Pro, the sight is set low enough that I can still use the factory iron sights, and is only a fraction of an inch wider than the slide. The sight fits the size of the pistol well, and has not affected handling at all. While there is some wear on the sight, overall the finish has held up as well as the finish on the pistol itself.The controls are easy to use, the sight window is generously sized, and the red dot is bright and clear. I set the brightness at 5 or 6, and have no problem seeing the dot in bright daylight, without being overwhelmed in a dark room. The shake awake feature works consistently, and the sight is always ready to use by the time I raise my pistol to take aim.The only quibble I have encountered so far is losing the battery tray retention screw, which apparently worked its way loose after two months of shooting and daily carry. Fortunately, Zulisy included a couple of spare screws in the box. I added a dab of loctite to the new screw before installing it, and haven't had any trouble since. The screw has not loosened at all in the last 4 months.Overall, the Zulisy Otter provides premium performance with a budget-friendly price.

I purchased this based off of glowing reviews I have seen from several YouTube content creators. Packaging is actually a nice change of pace from the "Tacticool" box art and design elements anyone doing any form of gun modification or accessory addition and dare I say Cute? Inside the box you receive all the tools you'd need to mount to an RMSc mount, and additional battery and a helpful installation manual. The product itself is a hardy micro RDS that holds zero extraordinarily well (with proper installation), open emitter design and has functioning shake-awake technology. I have been running this on one of my two EDC handguns and it hasn't deviated yet even after having dropped it, sat against it with constant pressure, and cycled roughly 75 rds. through it (9mm, 115 grain). This has been a gem of a RMSc RDS and I can highly recommend it for anyone looking for a budget option.

What an awesome red dot; it's a steal at this price.

Very much like this unit. Has features that compare favorably to a Holoson. Mounts easily, seems well made. Dot is clear, adjustments work, battery is easily accessed, and the kit comes with everything you need to mount on a compatable gat.

Completely died after a year and a half. Worked well prior to that. I thought it was the battery, but it's not. Thought it might be the "Shake to Wake" feature, but it's not. Just stopped working.

The Otter sight is made of aluminum, though the photos suggest otherwise. Like the side (rather than bottom) mount for the battery. Like the manual on off rather than relying fully on the shake awake, etc. Comes with a wide screw assortment so it's likely one will work for your pistol. Have not zeroed it yet, so I've held off one star. If you've never zeroed a red dot, do read the instructions before you attempt it. The adjustment is NOT intuitive and the positioning of the red dot in glass is deceptive relative to the point of impact.

Really like it easy to install and works great
