I recently finished a Ruger 10/22 build for plinking at the range. I had a Nikon 3-9 x 40 Rimfire scope on the gun but found myself using it at the 3x end and even then, the magnification was more power than I needed. For most of what I do, I'm under 50 yards so I wanted a red dot. I am currently using an UltraDot 30mm red dot on my Ruger 22/45 and it has worked flawlessly. I don't have the cash to spend on another UltraDot at the moment so I started researching other dots in the sub-$100 range. Millet came up time and time again as a decent performer in this price range.
I ordered it and it was delivered quickly. I was generally impressed when taking it out of the box. The build quality seemed excellent with a good heft and tight fit on the components. I was a little turned off by the screen printing of the logos on the tube. It was a little sloppy and pretty large (not like what is pictured). I can live with that, though. The finish on this sight is a rough-textured matte black finish similar to a parkerized finish on a shotgun (specifically a Remington 1100 with the synthetic stock if you've ever seen or owned one of those). While I wasn't super crazy about the supplied rings, they did tighten down firmly and the fit and finish on them was equally as nice as the sight itself. I didn't like the over-sized thumb screws on the rings for mounting them, but once tightened down, they weren't obtrusive and picking up an alternate set of rings wouldn't be hard to do if you didn't like the ones supplied. One of the best things about the rings is that they are top-bottom split rings, instead of left-right. You can lay the scope in them and its textured surface keeps it where you want it while you drop in the top half of the rings. The included hex key works for the ring screws, but doesn't work to attach the rings to the rail. You need a rather beefy flat screwdriver for the ring bases. It would have been nice if it were a one-tool setup. A small gripe, but worth noting.
My biggest problem came in with the dot itself. Please understand that I am not comparing this to an UltraDot. I paid far more money (more than 3x as much) for my UD, but I expected a better quality optic than what I received. Design quibbles aside, the dot itself just didn't live up to my expectations. A 5 MOA dot is fine for plinking. But a blurry 5 MOA dot is not fine for anything except maybe pointing at charts and graphs in a board room presentation. The dot on this optic was blurry and irregular in shape. The brightness settings left a LOT to be desired. At the highest setting, it was barely usable outside for the brief testing I did in my yard. Inside, I had to have it at 5-7 to even have a usable sight picture. This is unacceptable. I don't want something blinding, but I do want something bright enough to see outside. This isn't it. Finally, and this was the one that did it for me, I had a terrible glare in my optic. When looking through, there were several "tick" marks at about 10 o'clock. A sort of repeated ghost image of the dot. It was distracting and didn't go away with the shade or under different lighting conditions. I could deal with an uneven dot and even a dot that wasn't super bright. For what I paid, I would have been OK with it. But the ghosting and flaring causing the odd reflections were a no-go.
I'd recommend this for a kid's air rifle or something or maybe for a cheap gun that will be used indoors at a range, barring you don't have the ghosting reflections like I had. Otherwise, I'd pass on this one and jump up a price point to something a little nicer.
Lots of reviewers mention they've had their Millets for 5+ years. Perhaps they've switched manufacturers in that time, but this one was not what I expected. A definite fail and one I wouldn't consider unless you absolutely had to or you got a slamming deal on it at a local swap meet.
