Its loigical that a low cost brand is not high quality and generally disliked especially when there are far better optics in the same and similar price range ? price does not determine the quality of an optic , nor does the country of manufacture , what matters is quality control and build quality . Ask anyone who is at least a little experienced in firearms if this 150 msrp red dot compares to a vortex strike 2 and they will all say the vortex is far superior . if you haven ' t had a chance to physically take a look at these optics I recommend you go to a gun shop and ask if you can check them out , take note of things such as glass clarity , whether the dot is a crisp circle or a tiny red blob , what materials are used and where plastic knobs break easily , thin metal around the glass offers little to no protection in case of drop cheap metal and strip if you tighten your optic much onto the rail and ask the clerks what they recommend for your purposes and whysight marks aren ' t exactly known for reliability , battery life or quality materials or anyhting really other then being cheap . Its just a brand that companies like cabelas Walmart dicks etc can buy in mass quantity to sell in large numbers at the lowest prices to those who are concerned with price rather then value . I ' d argue a good 90 % of any optics in the 100 dollars range are intended primarily for 22 cal . , air soft , pellet guns etc , and are probably only sold in such large numbers because far more people are less knowledgeable on the subject and would rather save 30 dollars then spend some time doing research and buying something from a reputable company selling proper purpose built optics . if you want a quality optic but refuse to pay over 100 dollars check out bushnells trs 25 , they got for about the same price or a bit cheaper then this and have been proven to consistently hold zero on a wide variety of rifles including shotguns and rifles chambered in full sizecartridges , battery life sucks , glass is meh and the red dot disappears at the top left corner of the glassrealistically you ' d never be firing a gun at this angle anyhow , and this is for an optic many consider the cheapest quality red dotif you want something that isn ' t super entry level with a decent battery life clear glass crisp dots etc you ' ll be looking around the 150 dollar mark and I recommend , primary arms , holosun , or vortex unconditional life time warranty which is a huge plus imoTLDR get a trophytrs 251 x 25 mmreddotsight 3 moabs 731303 for same price and have more realiable optic or spend an extra 80100 dollars and get something REALLY good and buy a vortex
