foehn v2.5 BOB body
Sly Dual carbon "Jen" barrel kit
a new marker
Setting adjustments cannot be done on the fly
Cleaning is a dog
I bought my Ion brand new for around 260 about 3 months ago, Ive shot maybe 6 cases through it in that time, and my board is fried, now Ive been a smart parts fan up until now, but this is ridiculous. before anyone jumps down my throat about "oh you didn't maintain it properly, you did this and that and didn't do this and that" i took extra care of this marker because i cannot readily afford to buy a new marker whenever, i never over torqued a single screw being a mechanic i knew the importance of this, i was very careful about board removal and replacement after cleaning the internals (bolt, firing can, bolt stop etc.) (by the way WTF why would you design a marker for entry players that they have to expose the solenoid so often) short term i took great care of the thing. i go to the field to play the other day, buy paint pay my green fees, and the damned thing was fried sometime between my last play and then. not impressed needless to say.
Don't waste your hard earned ((or hard gotten from mommy and daddy) whichever it may be) on any of the junk smart parts makes, save the extra 100 too 200 and get a Dangerous Power G3 or G3 spec-R seeing as they have just been dropped to 399 on www.buypbl.com. you'll be much happier and it will actually come with a warranty. it doesnt surprise me that SP is going out of business.
