I haven't tried another device like this. It seemed difficult to use. After placing the bag, you need to press down hard on the edges to snap it in place. So much force that I thought it would break. You have to overcome the resistance of the rubber that presses against the edge of the bag.

1. The sealing is not always successful.
2. The user instructions are practically non-existent or even misleading.
3. The bags are expensive. It only makes sense for exceptional cases. Travel, etc.

I don't find any pros. What could be a pro? That, as some write, it does the job it is intended for? But that's why you spend your money! To do a specific job.
I'm sorry we have come to consider the obvious as excessive.

I do not recommend it because I see no reason for someone to seal bags regularly. If it does the job, one should look for more professional solutions. If they want it occasionally, they should buy a very cheap one, just for sealing the bag. Without vacuuming. Moreover, the contact of plastic with food is harmful. Only perhaps for exceptional cases is it acceptable.

wonderful..... does its job perfectly.... just not for continuous use because it gets hot (it did it on my 5 bags) and it needs very little time to work again, as it is not professional...

Small miracle. In manual mode, it seals and cooks food with sauce. I highly recommend it. I have been using it for 4 months.
