When it comes to red dots, Aimpoints are the Holy Grail and if you can afford one get one. But that doesn't mean that they're excused from making defective products. Do an easy Google search and type in "Broken Aimpoint", "Broken Vortex", or an other optic company and you will find forums of their products not working properly. Here are a couple of links:
This doesn't mean their products are crap. You have to remember that these products are being massed produced and assembled by humans. As we all know humans are not perfect. I can tell you right now, we are not perfect and Atibal has sold some defective units before but it's how our customer service handles the issue. The other factor is is quality control, you can minimize the chances of defective unit going out with high standard of quality control. Even that is not perfect, because guess who is doing the quality control? That's right, HUMANS.
Before Jumping off the "DEEP END" and saying this product sucks give the company a chance to resolve the situation. If the company does not, than you have every right to call them out.
Here is a review of us selling a defective unit and replacing it with great results:
"Couldn't be happier with the sight. Both the site and the company (customer service) far exceeds expectations. Bought this site and ended up having some problems with it shutting off over the course of a long W/E and about 500 rounds of 7.69. Called the company to return it under warranty and they seemed both genuinely surprised, and concerned that it was defective. I was all about just returning it for a refund, but they talked me into getting a replacement. I'm glad I did, the second one has been amazing and continues to operate exceptionally well after more than 1K rounds of 7.62, about 300 rounds of 12ga, and 500 rounds of 5.56. It's a great site. Bottom line, my Aimpoint is going up for sale and the proceeds are going towards purchasing a couple more of these so I don't need to keep switching it between guns"
We also had another issue with an MCRD but before we even knew about the issue, this customer went off the deep end. We did replace the MCRD but have not heard anything back from the customer even after we left numerous emails and voicemails to have him update his review. So... we assume everything is good.
"I got it March 7th and noticed that the red dot was blurry like looking at 2 red dots over each other so I thought maybe its because it was too dark in our room and so I will just wait til I get to the range. Today I finally took it to the range and the red dot looks fine, not blurry out in the sun. Shot my 1st 10rds (Ca mags) everything was fine. On my 2nd set the red dot disappeared after shooting 15 rounds. Hmm.. Maybe it turned off, power switch was not working.. Maybe the cap on the battery compartment came loose... There it is, the battery compartment cover was off and the battery fell off but wait... Thats not the opening where you insert the battery. It was the other side where it was supposed to be closed. The cover is hanging by a wire. Wtf Atibal?"
So, this just goes to show that Atibal, Aimpoints, Vortex, Bushnell, and etc will all have issues. No one is excused. It really comes down to how is situation handled when you do get a defective unit. Before buying an optic, you want make sure if they have a great warranty, good customer service, and that the defective unit you bought is not a prevalent problem (making sure that the good reviews out weigh the negative reviews by a big margin).
