The is one of the following ascenders, all sharing the same design with differences only in the color of the anodizing and in the markings.

I acquired the Asol, Version A and NTR, Version B as a pair, ordering them at the same time and from the same vendor in China. Interestingly, they were not priced the same. The Naxen also came from China. The Proverti CD 211L & CD 212L came to me from Poland and LACD is a German company, but I believe their ascenders were manufactured in China as well.
These are well-made ascenders and perform much like the Petzl Ascension. All sharp edges have been removed. The attachment points are simple holes in the shell. They have sharp edges that should be rounded with a file; even so, I would consider their small radius too sharp for directly attaching sling ropes. They are probably acceptable for webbing, but considering the proximity of the attachment points to the main rope, I would recommend using a small maillon for most attachments in order to reduce the risk of sling abrasion. The lower attachment hole could theoretically have the same safety problems as the one on Clog Version A.
The upper rope attachment hole is located very close to the main rope. A carabiner through the upper attachment hole will probably drag on the main line. Note that such a carabiner will prevent putting the ascender on or off rope, so one's climbing system must be designed accordingly.
I'm not sure the extra holes are needed at the base. Except for the Petzl Pompe, I've never found a real need for a second hole. Some people like them, and I might find them more appealing if they were large enough for a standard carabiner to fit through.
The ribbed handgrips are almost large enough to be comfortable for my large hands, provided I don't wear gloves. In any case, I don't climb by gripping ascenders at their handle. I think it is better to simply grasp the ascender from above and lift the ascender in the traditional manner (unless, of course, you are one of those who prefers to climb Frog).
The cam is very well made. The cam stop is placed in a position where it will not touch the cam if the ascender is off rope. I don't see much need for cam stops, most active cavers don't weight enough to bend their ascenders to failure by cam pull-through, and there is no need to shock load one's ascenders.
The tab on the safety is rather small and slopes downward, allowing one's thumb to slip off rather easily. The cam casting is designed so that it could be used with a plastic safety instead.
Although these ascenders are essentially identical, the acceptable rope size ranges printed on the ascenders varies from one to another.
This ascender has the same pit lip disadvantage as the Clog and other stamped frame ascenders, although the reinforcing will help prevent bending.
