Very nice quality - extremely good execution on the loading and priming mechanism. Of course performance is relatively lacklustre, but you're not buying this for competitive nerfing. You are buying this for the emotional response of realistically loading shells and having them eject, which this blaster does amazingly.
In my case there was a little issue with the ejection, but the Zhenduo Support team swiftly gave me a refund, as the issue was hard to fix without professional tools. Still this shows that they really do care about their customers and act professionally.

A cool blaster,
you can use the shells with gel balls and short darts.
I had no malfunction in play.
Unfortunately it was sent without the original packaging.
Not so cool, because it feels kinda cheap without it.
