This is a review for the KOSBON 47 PCS Electric Vacuum Sealer & Reusable Vacuum Food Storage Bags, purchased August 2020.
Updated one year after purchase. Rating downgraded from 4 to 3 stars. I was using the vacuum pump with the charging cable attached and I inadvertently applied a little pressure to the cable where it connects to the pump. This slight pressure was sufficient to break the cable housing inside the pump, rendering the unit useless. Granted, this damage could have been avoided if I had removed the cable before use. Nevertheless, I believe that the pump should be more robust.
I have had the product for only a few days so I cannot offer any long-term view. The product arrived complete, on time and as advertised. I charged the pump using the provided cable connected to a computer USB port. I tested the system using a small bag and the last inch of a home-baked loaf of bread. The pump worked as expected, it was easy to position the pump over the air-valve for the few seconds required to remove the air. The attached photos show the result two days after sealing. The pump was able to create sufficient vacuum to almost flatten the bread; and the air-valve held the seal well for the two days; so I am satisfied that the product is working as expected. There are many bags and spare air-valves in the set so I expect to get good use in the coming years for storage of different foods. A few minor points which detract from my complete satisfaction. 1. The set does not include a power adapter...... Be aware that, for charging, you will need to connect to an existing USB port (such as on your computer or mobile phone charger). 2. The charging port is deeply recessed in the body of the pump. So a standard USB cable will not fit ... do not lose the charging cable supplied with the set. 3. The instruction sheet has many horrendous typos. This does not affect the product functionality; but it does lead me to question the quality control used by the supplier.
While I really like having a vacuum sealer that is portable and does a great job. What it did to disclose is the difficulty of cleaning the bags once you have stored meat in them. I use dish soap, ran them in the dishwasher and also ran them through the washing machine to get the smell and residue of the meat product out. I even tried bleach to get the smell out after using the bags and of course, running them in the sous vide. It's a great concept, going forward I will be using a vacuum sealer machine which will cost less out of pocket than these bags, and no clean up needed.
Bags are ok. But the pump is total frustration. First 3 attempts over a flat are Nothing ; no suction at all. I recharged the pump. But no changes. So I try different positions. The only one that do something x me is placing two fingers behind the valve and after replacing them in different directions I’m able to get the pump to partially it’s work. Somebody from this item send their concerns so Iam giving my report. I decided from my end to buy a manual pump that comes with more bags...... so let’s see if I improved the suction. Bye the way I did first coking with my new Anova......I LOVE IT. I finished it in my bbq plancha. IT WAS PERFECT. THINKING IT IS GOING TO HELP ME WITH MY DIET
Love the bags that come with it, but there is a defect in the charging cord. The charger is ill fitted for the device. After plugging in the charger a few times the charger grabs hold of the inside of the device. When this happens the charger is no longer useful. I did return the device. I received a new one. I am not sure if it will last because the fit for the charger plug is not right. I am debating if I will send the second one back.
Works ok, but does let air in after about a week for non-flat items. For example, my avocado lasted so much longer in the fridge with this but after about 6 days, there was air in the bag. Didn't matter too horribly since you should use your avocado w/in that amount of time, but does make a little worried for freezer items.
I tried washing these bags by hand but there's always some particles or grease left behind in the bag. One side is textured to allow all the air to be sucked out but that makes cleaning them near impossible. You'd be far better off treating these as single use bags. Vacuum pump worked well!
I tried 2 bags so far and one of them lost the seal after a day or two, twice. Not happy with this but it's only one bag so far so I'll give it a chance and see if others lose their seal. Otherwise, overall quality seems fine.
