Customer Reviews



The build is solid and looks good. The gun is pretty accurate from a distance of more than 10 feet. I will update the review once I try hitting targets from a longer distance.


This Jinming Gen8 toy gun is a lot of fun. Our neighbors are buying one so we can “battle” each other. I see lots of neighbor fun with these.


I bought it for my nephew and he loved it, it is a great present and you can play it in different ways. Great product 👍🏼😃.


This is a great gel blaster. It is very easy to assemble and very easy to maintain. There are also many accessories you can add onto it such as the 1,000 gel ball capacity drum magazine and laser sight I have installed on mine.


I charged battery all day and only shot two bullets before it stopped working


Has great weight to it. Shoots very accurate up to about 30’ but will shoot about 65’ in total. Material is very nice and sturdy. Definitely worth the money!!!


I love this gun got it last week quick and easy reload, very accurate shoots far and hard i have learned this gun is a top tier gun one of the best on the market i would by it right now!!!


I like everything about this gel blaster I mean right out of the box it was ready to go sept for the gel ballad but I’m very satisfied with it


I loved the gel blaster, I just wish it came with more gel bullets.


Bought this gel blaster for my sons birthday. He loves it. It shoots very accurately. I thought I would have gel beads all over, not at all. The beads grow quickly and are ready to go. Its a very fun toy.


The velocity of the shooting is intense and fast - the orbi bullets hit so so so hard - extremely painful!! Left welts on my body under my clothes when my son playfully shot at me. Could easily damage eyes and really hurt a kid or adult. Machine gun noise also terrified our dog. This was an awful purchase. Regret this poor parental decision.


Really good and high quality gun, shoots really far and can hurt.


This is some real fun! It is high quality and can shoot really far. I highly recommend getting one, this thing is awesome!


This gun is fantastic has great aim has really strong power wouldn’t recommend for little kids it hurts pretty bad I’m close but far range is perfect


Had some trouble with it. Amazing customer service and they got me a new one and it’s perfect. 10/10


Looks great coming out of the box. Just cheaply made and always plugs up if not consistently shooting.


My grandson loved this gun. Unfortunately, I am not able to find additional magazines for him. He wants to have magazines ready quickly!


This gun has very good quality, i’ve used it for a little more then a week and have had no issues with it, does not jam at all. Just make sure you soak the balls for 5-6 hours for a better measure.


I own several different kind of gel blasters, this one is by far the best. Quality is second to none and it is endless fun !


If You’re Hesitant On Buying This BUY IT NOW!!

This Thing Is Awesome, Has Some Good Weight To It & Doesn’t Feel Like Some Cheap Plastic. It’s Very Easy To Assemble, There’s No Cleanup Of The Gel Bullets & It Shoots Great!
