This product works great. It was missing the refill container that holds the bubbles. We have to inpervise. My kids enjoyed the toy other then that.I love that this is so easy to use and that I was able to gift it to two young children instead of needing to purchase two separate toys. It does take a few pulls of the trigger to get used to the operation of it but that is because it isn't a continuous flow of bubbles once you pull the trigger but the kids gifted them loved the roar and small light show. I will say though that I would have preferred a larger reservoir for the bubble liquid as most of the kids I know love bubbles and go through it quick.The dinosaur leaks bubble fluid from the handleIt roars very nicely but the flow of the bubbles very slow and quantity low.I like them but hard for my three year old grandson to use. You have to hold it level to work rightThese were amazing. But my little one dropped his in the kiddie pool while playing with it. It shorted the whole thing out and even after drying it doesn't work. You'd think with bubbles being water it could at least stand being dropped. Be also warned that the noise level is a bit loud. Kids loved them till they died.We were expecting 4 bottles of bubbles with our two bubble guns but received only 2 bottles.Stopped working after a few days. Seemed to blow out air, but no bubbles. Tried new bubble mix and new batteries but still did not work.Do not recommend this product. The bubbles on both guns just rather at the front of the Dino guns rather than being blown in the air. Ideally I would return but left it to late as bought in advance of my little ones partyThese work really well but they completely stained the childrens clothes! Took a few uses before we realised they were what was causing the stains, won’t come out either so not worth the cost of replacing outfits! Maybe worth using only in swimming togs or something!Kids were very frustrated with these,they didn’t work more than they workedHabe einige Pistolen ausprobiert, alles das selbe am Anfang gehts, sobald man die flasche nachfüllt fängt es zum schäumen an und rinnt nur nochPROS: buen precio, buena calidad, un regalo perfecto para un niño que seguro pasará buenos ratos jugando con ellas.CONTRAS: seguramente se ensuciar un poco el hogar pero siempre es así con los niños y las pistolas tienen efectos de sonido lo que puede ser molesto para algunos padres.
