I though the bazooka tool would save me some time, but in fact it makes process longer + you have less control over the results + more cleaning.
1) Rolls are way too big. 2) Rice is sticking inside and on the edges, so you have to clean it continuously during the process. It makes it harder to close. 3) Pieces keep disconnecting from each other 4) Plunger is not tight enough, so sometime it pushes fish out of the rice and your rolls are ruined. 5) The rolls produced are longer than standard nori sheets, unless you press it from both sides, but there is still no indicator what the right size should be.
The knife in the set is not sharp and because it's painted, sharpening would damage the paint and make it not food safe.
My advice: just practice making rolls traditional way, apparently it's not that hard after i watched a few videos.
