VsTank Pro have their plastics made of the best possible quality. The same goes for the Tokyo Marui tanks as well. If you're playing a little rough, the tank can withstand a few heavy contacts and the parts won't break or fall off easily.

That's not the same with Hen Long. This thing is so brittle that simply trying to bend the small parts can break it off. This 'feature' extends to the 1/16 scaled tanks they made as well. A bit of contact would have their parts knocked off into the air easily. It is also rumored that Hen Long uses recycled plastic for their tanks as well, thus the poor quality.

On our Hen Long sample we found out some glaring flaws on the tank's plastic body. There's a piece sticking out of the tank's rear. That's not what exactly you'd like in your tank. Also note the loss of paint around that piece as well. In another picture, you can see the assembly quality is quite low, the rack at the back of the turret fell off.

(Left) Note the extra piece of plastic right next to the rear light as shown. (Right) Note the rack which has fallen off, due to the poor plastic quality.
