okay, so once you get around the fact that it's made of really crappy plastic and you're not going to go out of your way to enforce a lifetime warranty (because, although it hasn't broken after my 1st use, it's guaranteed not to last more than 3 or 4 tries), it's a fun product and it does work.
The knife has a plastic handle and the blade is NOT that sharp. I think they try and upsell you with the blade, and I was really let down by its performance.
just keep in mind, you get what you pay for hence not a 1 star review.
when I opened up the bazooka I noticed a ton of red plastic shrapnel which then caused me to examine every edge to make sure I wasn't going to be eating this plastic which i'm sure is not BPA free (don't quote me on that).
I think, before you buy, watch a couple of youtube videos and determine that all you may need is the bamboo rolls.
