I had many of their bodies go through my hands. Here is the deal. They offer two kinds of material used for their bodies. One is regular lexan and one is some kind of plastic more like PVC mix. The regular lexan bodies are quite good, those bodies have matt finish protective overspray ( similar to Tamiya bodyshells) thats how you can recognize them on their pictures(also by the much higher prices - around 21 USD or more). The details on the mold are acceptable ( almost like HPI bodyshells). They all have protective and some also basic detail decals and lightbuckets.
The other type , with PVC type plastic, are much cheaper , most of them are without any decals or light buckets, just plastic set of same 2 type rear wings, windshield wipers and side mirrors. They are quite easy to bend while grabbing the whole car with one hand, but they also endure many crashes. THose are perfect basher or training bodies. I have been painting them only with water based faskolor paint and they hold the paint perfectly. THe negative thing is that you have to make your own protective and detail stickers. I have my sistem of doing it and they come out really good. It just takes extra 1-2 hours. The details on their mold is not as high as brand name ones but , believe me, from 1.8 m distance ( regular person view point) none would notice big difference. Some molds are from Yokomo , some from HPI, and some from Tamiya originals. THey also have some that are of their own, that are issued only by them.
It all comes out to this: you probably have in your mind bodies that you would like to have. If you are beginner in all of this or big time basher(training freak) got for the cheaper bodies if they have them. If you are more experienced driver( painter) than go for more expensive type of plastic ( ofcourse if they have them in higher grade plastic). ALso be sure to check prices(and shipping) with original brand of the same body. If the difference is less then 10 USD go for the original. Because it probably is a better detailed body and much more detailed decals. FOr copies of YOKOMO bodies almost always is worth to get the cheap copy, easpecialy if it is going to be heavily used in crowd of other cars. In case if you are making body for photo sessions, shelf queen, concourse winners than originals are the easiest way to make such body.
Here are few examples of their bodies.
