Excellent value
Wanted to go to a 1x setup but my original crankset had riveted chain rings that weren't easily removed so I went the easy route and swapped them out to these. Very nice fit and finish. Not too heavy, not too light, just right. Chainring works well with narrow wide multi speed chain and hasn't skipped a single tooth. Would recommend for a very budget friendly crankset swap or upgrade.

Works as it should
Got this to replace my bike's chain wheel, and this was really nice. Works well with the other pedals I had also gotten.

Gambled and Won
I decided to gamble and try this cranksets on my computer bike and do far it looks like great choice and it cost me under $39. I have looked at a number of 1 x cranksets with most of them costing over $150 dollars.

overall nice crankset, but one little easily fixed problem
I got this is in a black and silver round 40T version. overall I like the style and it was easy to install I also installed a Bucklos square taper bottom bracket at the same time. pedaling is easier and my bike is about one pound lighter due to removing the old 3x chain rings and front derailleur. the one thing I did encounter was the left side crank arm would loosen up, I tried red and blue thread locker on the 8mm bolts it still came loose, I tried the long and short bolts still loosened up and I made sure they were tight but not over tightened due to the aluminum crank arm. I ended up fixing the problem with replacing the 8mm socket bolts with Vanice M8 x18mm crank arm-bottom bracket bolts, these have ridges on the under side of the bolt head to help the bolt grip and I used red thread locker and let it set overnight so far it has not come loose. overall I do like the product. For the record I did not contact Bucklos I figured there was an easy solution and I really didn't want to replace a lot parts I just installed.

Nice crank set!
Fit perfectly on my bike..easy to add the chainring. It even came with the bolts to attach a chainring.

So far so good.
I haven't ridden the bike on any trails yet but the crank chainring is smooth. No skips in the chain when pedaling. The bike overall looks cleaner with out the front derailleur and multi chainring crankset that were on it.

WIDE chainline, holes not centered, chainring is garbage
Mounted up with a narrow 113mm bottom bracket and still had to mount the chainring to the inside of the crank arm just to get a 52mm chainline(3mm outside of ideal, but still in the acceptable range). The chainring mounting holes are not centered in the crank arm. This just looks bad, especially since I had to mount the chainring to the inside, making the badly positioned holes totally visible. The chainring has an almost hooked shape to the narrow teeth and the chain jumps very badly in the largest 5 gears and the smallest gear, meaning I only have 3 usable gears that the chain won't come off. It doesn't matter which direction I run the chainring, either. I am very disappointed overall. I am going to try a different chainring to see if it works any better. I thought a "Narrow-Wide" chainring was supposed to retain the chain better, not throw it off worse!

Upgrade time!
My Mt. Bike is 5yrs old and needed some over due maintenance and made pretty. Everything arrived in a timely manner and undamaged, as does all of their items. They had most of what I needed for upgrades (everything a magnet stuck to had to go) along with pedals and the up grade to 203mm rotors (don't stop here, check out the whole store) I'm probably going to them for my front shock and head set in December.

Very easy to put on the bike. Seems to be good quality. Let's see it with time!

While the crank arm/chainring set looks like a nice product I am unable to install it on my bike and see how it preforms and holds up to use as the set arrived without the 36 tooth chainring I picked. Very dissapointed.

a little lighter than the stock crankset on my cheap fat bike. they look nice. would have been nice if they came with crank bolts though. they went on nice and tightened to 40nm no problem. chain ring seems of good quality and fit the chain nice. one thing to note: the BB shaft is a different length on either side(non cartage BB). chain line was way out when i installed it... simply by turning the BB axle the opposite way corrected it. if you have a non cartridge BB it works. obviously if you have a sealed BB(cartridge) this doesn't work.
