Bought a Matrixx system, including the filter, sized for our rural home. Replaced a C------n system, whose new model would have required re-plumbing anyway. The old C---n system had worked for 32 years, having to twice replace plastic gears cannibalized from carcasses in their junkpile, so I have no complaint with them, just that the new model was almost $900 more than the Matrixx, and actually more system than I needed. Also, one other local competitor was still $500 more, including the cost of re-plumbing materials.
I was able to install the system using my existing skills, their VERY GOOD VIDEOS, and flex couplings from Home Depot. The only problem, and minor at that, was with the flex fittings threaded into their filter housing - had to use a LOT of joint tape and add a second and third smaller wrap in order to get a good seal - can't "fill" enough with one wrap without leaking. Also a minor omission on the brine tank hose - they drop and don't mention the small ferrule, which is inside the fitting, so shouldn't be a problem if you're careful.
The system shipped VERY rapidly, and was to Virginia in three days via UPS. Only complaint was with the box containing the resin. When it was dropped, somewhere enroute, the weight of the resin split the poly bag, but fortunately, almost all the resin was contained within the carton, only leaking a little bit out. They need to doublebag it or otherwise pack more soundly. It might also be helpful, when appropriate, to include a label which clarifies whether or not one's system uses gravel as well as resin (ours did not).
So far, we are getting excellent water (we have a deep jet well and approx. 8.5 grains hardness, plus a little iron-sulphur smell.) Our brine tank is in basement with its bottom approximately 11ft below the "head", but it appears to be 'drawing' brine, as reassured by one of their customer reps before I purchased the system.
The system is fairly easy to program, if you follow the video carefully. The only more obscure piece is on Level Two demand cycling, which is found later in one of the vids other than the initial setup - you just have to look for it. We also included the resin treatment add-on kit for the brine tank and a large reserve supply of solution, hoping that will extend the life of the resin and significantly postpone any need to replace the resin, down the line.
IN CONCLUSION: A reasonably-priced system when it was on sale, and can be installed by anyone with basic tools and mechanical skills.
We'll have to re-post if the system does not have a good lifetime.
