I bought these firecrackers to a gun of my 3 year old son and a half. He had some firecracker purchased in supermarkets (here is rare), and when it had none, I decided to take in large quantities here for he has ahead. I do not pay attention to the buying, there decibels written on the photo: 125 db. It is not specified in the announcement, but it is checked by receiving. Caution ears !!! My son does not expect much noise and he even got scared and no longer plays with his gun so much noise bursts your eardrums! Nothing to do with the previous firecrackers purchased in supermarkets and certainly contain less powder. They were quieter and more suitable for children. Be aware: 125 dB is the sound of a jackhammer! Ok, the sound lasts a half second and not lagging in length, but believe me, here resounds in the eardrums and it is better not to have the gun close to the ear. Even I am an adult and with an ear better trained than that of a child, I feel the pain hearing. Knowing that there are much less strong on the market, I advise against it and recommend those people to buy less high paying attention to the noise generated. These are not the cheap, work well, the product has no manufacturing defect, but it works too well and too strong. Protect the ears of your children!
