Customer Reviews



Bought this blaster as it had good reviews. Item has been delivered in 2 packages. First was in a plastic bag, with 1 item damaged ( 2 items in bag). Second had the rest, with battery charger damaged ( squashed on end and bent) and rifle looked as it wasn't new ( fluff and dust on the inside parts).
Battery charger arrived squashed and bent on the end and I had to use a small screw driver to open it so I could plug it in to start charging the battery. Asked for a replacement one but no answer so far.
Delivery was OK, time wise. Considering it was coming from China.
Haven't built the rifle yet (as came in multiple parts instead of 2 as shown in the videos online...) but will have to do it quickly to check if it's OK, as doesn't look like new. Was expecting better quality though. Had the m4a1 j8 and the quality was good so was expecting this one to be better but it seems/looks/feels like the same or less. Disappointed on that aspect.
Still waiting on my "upgrade" parts, which I hope are going to be of good quality materials. Fingers crossed...
All in all not impressed really so far. Will do some testing of the rifle and will report back here and on trustpilot when done.


how long does this gel blaster take to come to America?
Service:around 2-3 weeks


The overall quality and workmanship are very good, the ballistics are stable and the strength is great. gen9 is the best!


¡increíble! el J9 es genial, tiene un largo alcance de disparo y una velocidad de disparo muy rápida, ¡lo recomiendo!


awesome! the j9 is a like a killing machine, 2x performance than the former blaster, the construction is hard nylon.


the gen9 arrived quickly, full nylon made with powerful v2 gearbox. i will test it tomorrow and then write a review back
