At first I'm concerned about strength and durability. Until really put it in a harsh test did some small jumps fast technical descent hit some rocks here and there 2-3 ft drop and a lot more. This wheels earned my trust! Amazing wheel. The hub? super smooth rolling.
Weaknesses: All the positive reviews here seem to be 'as new' reviews. I have approx 4200 miles on these wheels which, came with my Niner Air9 RDO. The wheels only lasted 1 season. On the rear wheel, the rims have failed - cracks around spoke eyes and spoke pulling out 1-3mm on eight of the driveside spokes. I am a 175 xc rider. I have owned several 'light' wheelsets before. Typically, my Stan's ZTR rims will go 2-3 seasons before I've had to replace them. Other - compared to nice hubs (Dt swiss, King), the engagement is terrible. Once you switch to these hubs, yes, you will notice. Finally, I had tough time getting multiple tires to run tubeless. With Stans, you can deflate the tire and have to exert pretty good effort to remove from the rim. With these, if you loose pressure the tire simply falls off. Can you say 'DNF' if you flat during a race?
Poor rim durability (1 season = 400 miles) rim eyelets have failed.
Hubs still low quality
Poor ability and robustness to run tubeless.
I've been using these wheels for about 50 miles per week for the last 6 months or so while riding smooth XC to rocky small mountain trails. I weigh 150# and ride fairly light on the bike. Thus far my only complaint is the "plinking" noise that they make. They did it when new and under warranty, AC graciously re-tensioned and relieved spoke wind-up and the noise went away for many hundreds of miles. However, recently the rear has begun to plink again. They have stayed in true fairly well but suspect I am losing tension again, probably because of their light build. If they didn't make this noise I'd give them 5 chilies for sure
Thought I'd post early to bolster the info available. These wheels seem pretty sick. I'm about 195 and can be rough on wheels. I'm riding a h/t 29er with 80 mm Reba up front. Although I picked my lines and threaded some rocks maybe more than usual I didn't ride any slower or less aggressively. The first ride was to the top of Green Mt. here on the Front Range and right down Box of Rocks, a baby head strewn descent that's maybe 2 miles. The next was a bigger 40 miler up Gold Dust out to Bakers Tank and down into Breckenridge behind the ice rink. Then back up Moonstone and out Boreas Pass to drop back into Gold Dust-an 8.5 mile mostly downhill through variable smooth to rooty and rocky single track. Although I picked my lines a little more than normal I didn't really hold back on the wheels. They are noticeably faster and really stiff. It was odd feeling the stiffness but not really feeling any weight. I am running Specialized Captains with the Control casing at about 35 psi. Next ride I'm going to back off the psi just a bit but not enough to clap the sidewall down to the rim. I'll report more if these things crap out but I'm pretty impressed out of the gate. Very noticeable acceleration and way faster up hill. I pushed a higher gear than normal and they felt like they still had much less resistance than any prior wheels. Really nice wheelset. The hubs are really quiet and engage reasonably well. Not like Kings but probably better than the Hopes. Way quieter than either of these if you're into quiet. I kinda like the clicky scream of a loud freewheel though.
Strengths: Wide, Light and very strong. Lots of axle options.
Weaknesses: A bit polarizing in the graphics department.
Weighed in at 1422 grams. I got mine with a 15mm front axle and a 10mm rear. They arrived in the box without the included AC valves. AC was notified and they sent out a set right away but it still took a week of ground shipping before they arrived. I weigh in at 205lbs and wanted a light weight wheelset that could handle my heft. I am pretty nice to wheels as I ride and I wasn't anticipating any problems. I have hundreds of miles and several races on them now and I feel like they are a great wheel set. They replaced a set of DT Swiss wheels on my race bike and the difference in weight and perceived spin up is noticeable. Initial set up for tubeless was a mixed bag. The front, a Schwalbe Rocket Ron, went on easy and aired right up. The rear was a different story. I am using a Maxxis Aspen and after several failed attempts (very loose fit), I finally installed a tube, snapped in the bead, removed one side, pulled out the tube, installed the valve, removed core and fought with it for another 5 minutes before it snapped in. So far they remain very true. I did have a burp flat in Moab during a race. It initially burped once (rear, on off camber rock, running 24psi) but remained solid enough to ride on. About 10 miles later it burped again and was just soft enough to tap the rim. I had to throw in a tube at that point. Comparing these to carbon, I no longer feel the draw of a carbon wheel. They are plenty stiff and just as light. The price is perfect for what you get. Disclaimer: I did get these at a great discount. I highly recommend them.

Strengths: Super light.. Wide rims (28mm) to work well with lower PSI tubeless tires. Looks! Love the black/white/red color combo.
Weaknesses: They say "Tubeless" in large font on the rims. Is that really necessary??
I've had these for a few months now with over 500 miles on them, including many 40+ mile days in the saddle on rough trails. They are true as an arrow. They are a great substitute for carbon wheels costing over twice as much. I weigh 175 lbs and ride aggressively, and they're holding up fine so far.

Strengths: Light weight, wide rim, ready for tubeless
Weaknesses: None yet.
The wheelset is advertised at 1417g and mine weighed in at 1430 with pre-installed tubless rimstrip. The rim is also quite wide at 28mm so your tires spread out nicely for maximum grip. After riding everyday for over a week, the wheelset remains true and straight. The light weight is noticeable on climbs (hard to believe their 29ers). I also like the fact that American Classic uses steel liners on the otherwise aluminum cassette body to prevent notching.
As their name suggests, this wheelset is designed for cross country racing. I don't plan to use them everyday but wanted to make sure they work before the season starts. Probably not worth the MSRP is you're not going to race on them. Great value if you are.
Getting ready to pull the trigger on one of these and any input/info/opinion you have is welcomed.
