Weaknesses: Prone to leaking, craftsmenship of the accessories, and ergonomics of on/off buttons.
Review: First and foremost, I want to caveat this review with the premise behind my judgement being "bang vs. buck" relative to other markers and their market prices. Secondly, my likings for certain aspects of this marker are based on PREFERENCE. Lastly, i'm not going to mention anything on accuracy, or the capacity to shoot fast, because practically every electro marker today shoots faster than the amount of wood a woodchuck can chuck wood. Most - if not all - of us should know by now that in most cases, accuracy is a function of the barrel/paint match (including the quality of the paint, i.e. having higher standard deviation ratings than most or all other paint), and shooting consistency of the gun.

This DM7 is quiter than all other markers i've owned, with all things being equal (barrel, measuring range, etc.). The kick is also significantly less than any other marker i've used, except my SL74, which it seems to be on par with on this front. When holding and shooting, the feel leaves nothing to be desired. The longer distance between the inline reg and the grip frame allow me better leverage changing my aim laterally from target to target, and raising it from hip to point of shooting. Lastly, the mechanical design of the entire gun, from air-in to air-out - in my opinion - is ingenious. I love how the air that's used to push the bolt forward seamlessly transitions to becoming the propellant of the paint balls (hence the lower kick and quiter sound).

Granted the nice build quality of the body, the accessories (LPR cover, bolt cover, on/off air plug, feed-neck lever, and trigger) have relatively poor build and/or material quality. Yes, the quality of these items do not impact the function, weight, or look of the marker overall - they're quite trivial in the overall scheme of things; but if i'm gonna put 1400 into a gun, such "trivial" parts should have the same or better build quality relative to other hi-end markers. And then there's the pet-peeve of air leaks. After numerous occassions of switching out advised o-rings, leaks would persist from the same locations. More often than not, the leak repairs have come on their own. But most of the leaks i've experienced have come from the bolt and bolt assembly. But, after many times of taking this module out, apart, and re-installing, i've caught on to the culprit. So, at this point, leakage is far less of a problem, but still somewhat of an annoyance. The only reason why this problem is included as a factor for my rating is because of the numerous threads i've come across that emphasize this same problem; otherwise, I would treat my leakage problem as unique and inconsequential.

Lastly, the ergonomics of the on/off & settings buttons aren't user-friendly. The response of the small, ball-shaped buttons leaves something to be desired. It would be nice if the buttons had more area to press.
Conclusion: This marker is great! I love the feel of it - that it's smoother, quiter, and more "leverageable" than all other guns i've used. To me, the SL74 and it's lighter weight does have an impact on MY performance; but i won't let that impact my rating of this gun - I won't penalize the rating of this gun 'cause i'm too much of a wimp (haha). Besides, to some, the extra weight may be more advantageous. Getting back on track, relative to all other guns, the price, widespread leakage problems, and quality of those included parts (that cost $100+ as an accessory kit) does not seem to be inline with a perfect rating. Two ways of getting a 10 from me: hold everything the same and decreasing the price to $1k, or keep the price the same, but remove the leakage problem, increase the quality of the accessories, and improve the ergonomics of the on/off buttons.

YEAH for all the DM7s owner if you have leak problems use more grease. I mean use a whole crap ton. This gun isnt like a ego or a spyder f.o.s.o.r type gun or or w/e this gun has no springs that move. As this reviewer stated the bolt only is moved by air...,That said it moves the bolt and only the bolt moves, it needs alot of grease. Your leak problems are your own gun care problems. The manual says use a generous amount of grease on the bolt and a thin "layer" on all the orings. ALL ORING in ALL GUNS can go bad. They are little pieces of rubber,,, come on.....egos are bad ass but a sl74 is 2grand 800 bucks more lol . I can get a macdev and a dm7 for that. USE 2x the amount of grease and put in new oring that havent dried out then you should be fine.everything this guy says is true and he says his leak problem is unique,but for the rest of ya MORE GREASE!!
