WE 25rds Magazine for WE, Marui, KJW M9 M9A1 M92 M92F / Samurai Edge GBB -Silver [for Airsoft Only]

So already having issues even getting this due to shipping glitches, which may be the reason why the low reviews ( I mean UPS had the same thing but I still got my stuff 2 days in advance...) but I digress let's get to the product.So out of the box comparing it to the one I ordered from the evike (evike product on the left, Amazon product on the right) shop they are pretty much the same....except in price. The weight is good and sturdy, the valve for the green gas is functioning so far and the spring is well springy. My only confusion is why so much more expensive on one site and not the other and I mean by base prices alone. I would only recommend to purchase from Amazon ONLY IF it is unavailable ANYWHERE ELSE.The only reason why I gave this a 3 out of 5 was the process of even getting one to actually ship and stay within schedule/process of the shipment (Customer service from amazon was able to fix this, thank you) and that it's more expensive to buy on Amazon than on the evike shop.Other than that, this works.....
