Customer Reviews
Thank you for what you do
Moderately satisfied; as soon as you make more than 50 bags, it overheats and smokes.
The sealing power seems adequate; I had a Raja before, and it worked better despite having slightly less power.
It wasn't the same price either.
As soon as there's a little moisture, it doesn't seal well.
It’s very inexpensive, it works, but you get what you pay for.
For a hobbyist who processes small batches with very clean bags (hopper required), it’s okay; otherwise, switch to a different model.
High-quality product
