I think everyone is curious as to the reliability of a new marker before they purchase one. and are entitled to an honest answer.
Anyone who has a working knowledge of markers and has looked into the luxe will know its based on the shocker platform and that like most spoolies will not have any issues if looked after appropriately.
I'd expect anyone looking to spend a thousand pounds on a paintball gun of all things to do some actual research into what they are buying, rather than ask some strangers on the internet. I know I would.
...actually I wouldn't, as spending more than 250 on a paintball gun is a ridiculous decadence imho, but then the value of things are very subjective.
But end of the day It'll be no less reliable than most over spools, but no more reliable either. But it will speak to you.
