This is not a 'full review'; you state that yourself in the video. You state the manufacturer's claimed shot count, but didn't verify it. That's one of the purposes of a 'full review', to see how well the product actually delivers vs the manufacturer's claims. By stating the shot count in the subject, followed by 'full review', it makes readers think that 1) you actually measured the shot count, and 2) it actually delivers the stated count.
Also, you state that you filled the gun using a hand pump and that it took 'about 50 pumps'. I hand pump my air rifles, and single reservoir guns take many more than 50 pumps to refill after being discharged down to near the regulator pressure. This gun, having three bottles, most certainly takes waaaaaayy more than 50 pumps to fill. From a discharged condition, I would guess this would probably take me three pumping sessions spread out over 15 to 20 minutes using a hand pump and probably between 200 and 300 strokes. And sucking a lot of wind in between - haha.
Your video might be more accurately titled as a 'first look' or 'fun shoot', not a full review. If you want manufacturers and viewers to take you more seriously, you must pay attention to accuracy in your details. Otherwise it seems like clickbait and viewers are left wanting.
Good luck with the growth of your channel, I wanted to help you understand how to improve a little bit. I know you have struggled quite a bit with air compressors for gun refills and all these things cost money. But first and foremost, integrity builds your reputation the best. The rest of the good things come after that.
