crabshooter: I bought this sight with prime shipping on January 24th and received on February 6th, after waiting nearly 2 WEEKS, not days as promised I opened it up put the battery in (properly positive side down) and.....Nothing!. Went online and read that the supercapacitor may have to charge and to leave the sight under a light for a couple of hours. I left it under the light overnight and...nothing! Aside from the fact it's a paperweight it seems well made; I really wanted it to work and may exchange, although it seems like I'll be waiting a while.

Edit:

I ordered another sight as the reviews here and elsewhere are overwhelmingly good. The second works the way it should. I have a stigmatism which is why I bought this, the dot is nice and clear, you just have to adjust the brightness to get what you need. I like the shake n wake as well.

AttaboyAdley: I've been so pleased with my experience with my Holosun 503CU that I wanted to take the time to leave a review for shooters that have Astigmatism.

If you've used a red dot sight (RDS) before and the dot appears blurry, smeared, or in a starburst - then you probably have Astigmatism. A quick way to check to see if the RDS is working fine is to take a picture through the optic with you camera phone and see if the dot is clear. If it is, then you'll know it's your vision.

I wear contact that treat my Astigmatism, but they do not completely nullify the effects. I typically see a small starburst - it looks a lot like a dot would appear if the RDS brightness was turned too high (dot gets fat aka "blooms").

So, why do I recommend the Holosun 503CU a great, budget-friendly RDS? I've tried a Vortex Spitfire AR, Sig Romeo5, and the Vortex Sparc II AR. For just about $40 more, you can get a solar failsafe feature, Shake Awake, and the option of switching to a 2 MOA dot and or a 2 MOA Dot/65 MOA circle. That alone was worth it. The Spitefire was supposed to help people with Astigmatism since it overlays on a reticle (red dot and MOA circle options), but it has restrictive...

Amazon Customer: I was keen to test this sight out after great reviews and testing it mounted for function of use buttons etc. Then I shot with it....
Mounted on a 9mm carbine I thought nothing of it being able to handle recoil.
First shot ...I saw it close to aim..2nd to 5th hey I better move point to right. 6 clicks another 5...another 4 clicks...point of impact still way off.
I didn't have paper up and continued to shoot,noticing sight was way to the right still.
Total of 40 rounds I thought I'd better do sight in proper with paper targets and a rest. I was putting the gun back in case when I noticed the front lense was slanted to the right and the lense edges looked flecked like broken glass. The lense had popped out of the retaining ring on one side and slanted to shooter right. I'd say almost 1/8th ! This is a lense smaller than an inch!

I'll leave it in current state and see about a replacement.
Love the look the solar backup ,long bat life,adjustability, weight everything else but the lense posing out so 2 stars but if this was on a 12 guage it would've been a possible shattered glass.

Stephen Turman: I just built a mid-range AR a couple of months ago that, to my surprise, is capable of 1 moa accuracy with quality ammo and, assuming, I do my part. I have primarily been using a Vortex Strikefire and TRS-25 on my earlier builds, which were fine. This cupcake (I named her Hillary) deserves better since she is going to be my gtg, shtf, wrol weapon. I originally was looking into getting an eotech--since I really love the circle dot reticle. However, I don't love the bulkiness or battery life of the eotechs and prefer the form factor and ridiculous battery life of the Aimpoint Micro H-1. You can't get an aimpoint with a circle dot reticle though and, frankly, my wallet really couldn't handle either an eotech or aimpoint. So, hours of research later, I decided to go for the Holosun 503CU.

This Holosun 503CU sight is fantastic. It's like Aimpoint and Eotech got drunk one night, screwed the crap out of each other and had a baby!!! You get the Eotech's circle dot reticle (actually the Holosun's reticle is sharper/better than eotech's) in the form factor of an aimpoint H-2/T-2, except Holosun ditches the bulky side battery compartment for a slide in drawer style (better form...
