Umarex MP5k: Should I cancel my order?

[FireWizard44]

Hi,
I recently ordered a Umarex MP5k, but I’m having second thoughts after reading reviews stating that it wasn’t worth the money and is a piece of junk. For anyone who’s ever owned one, would you reccomend it, or should I cancel the shipment and get a different gun instead? 
Thanks.

I’d wait for the Crosman Model that looks like an AR. I had the MP5 being an HK fan boy.. it’s a decent little gun but I didn’t enjoy it too much.
