In short, if you are on a budget, it is a good rifle for under 400$
If you plan on upgrading it, it is a good rifle, as almost all the "important" parts will be swaped to upgrades anyways.
The big difference over a Maruzen APS-2 Type 96 (the gun this clone is based on), is the finishing quality. There is nothing a good sanding and a fresh coat of paint can't solve.
Some internal bolting point might also have to be reinforced. (It was the case with my Well G22, mostly the same rifle, just gaz powered and different stock)
