ease of maintainence
Well I picked up one of these brand new for 300 just before the price went down to around the 200 ish range. Without a doubt this gun, out of the box, beats any other marker in its price range. I recommend it to anyone who is looking for a marker that performs as well as the guns in the 400-800 range, but price wise is at the level of the ion.
Let me start off by talking about the maintainence on this gun. Taking out the internals takes literally a few seconds to take out clean. Just a pull of a pin and a quarter turn of the back cap and you have your hammer and bolt removed and ready for cleaning. Breaking down the entire gun also takes only a few minutes unless you don't know what you're doing. It's a very simple gun, not much intricate milling or air passageways involved. Also no internals hoses to worry about. Not too much to go wrong on the inside, only one o-ring to lube on the ram and then the two o-rings on the ram housing.
Efficiency is pretty solid on the gun. I haven't really done too much efficiency testing on the gun at this point, but it definetly beats either my shocker or dm5.
The stock electronics are great. It comes with plenty of firing modes for various tournments and 25 bps cap for just playing around at the rec field. The gun will shoot up to 25 bps and it is impressive to see it accomplish this for only 200 bucks and no upgrades added. The eye logic seems to be flawless, i've had many barrel breaks due to bad paint and plenty of broken paintballs in the hopper before and the eyes didn't seem to go down even when paint did get into the breach. Not sure if i just got lucky or not but I will continue to look into that. It's also an optical trigger with a spring return so it has a nice feel to it if you like optical triggers.
The trigger is only two point adjustable which normally wouldn't be a problem, except the gun does have a problem with bounce. Even just clicking the noid on semi, it's possible to have a full auto effect when you pull the trigger and it's very easy to do. only way to help this problem is adjust the trigger but it can only alleviate the problem, it won't cure it.
On another note, the board on the gun is, at this point, out of date in that the psp and millenium modes are capped at 15 still, so if you want this gun for tournaments then an upgrade in electronics is a must. Also there is no other adjustable settings other than firing modes so fine tuning is limited.
one other thing that i have found that isn't really a weakness is the lpr. I've heard of people taking out the lpr (low pressure regulator) and swapping it out with an F8 front piece (not a low pressure regulator). So at one point i decided to gut the internals from my lpr and see if the gun still functioned, which it did with little if any decrease in performance. so the lpr on the gun is really useless in a way, but its a nice safety feature to have so i wouldn't recommend messing with it like had.
other than that this gun has been great for what you pay for
I highly recommend this marker if you're looking for a fast, easy to clean, affordable marker. it's easier to clean than most if not all high end guns out there as of now and its affordable, but grab one while you can because you can't find too many of these brand new anymore. If you're a tournament player i would pick up a new board for this gun as well, and seeing as how it was able to go 25 bps stock, then putting in something like virtue in it would be absolutly insane.
