I did a heap of research for the other available vacuum sealers and this Vevor item had the best price, vacuum suction, bag size, and other features. The double seal is hard to find on other models. The unit itself is very sturdy and well made. It's a good size for sealing even quite large bags of food. However if you keep the box it comes in, you can easily pack it away and it's easy to store. I've used it multiple times and am very happy. I also think all the functions it has are really good (and I've used them all): wet/dry, manual vacuum and manual seal have all been really handy. This is the second product from Vevor I bought and both are really good. What you get for what you pay is truly great value.
