SOUL HAND Soulhand Vacuum Coffee Canister Automatic Airtight Coffee Containers & Food Storage, Glass Coffee Jar with Spoon, Touch Screen Coffee Storage Container for Coffee Beans/Sugar/Nuts 1.6 L

Vacuo com boa pressurização, mantem a qualidade dos grãos com menor alteração das propriedades do café, devido a menor exposição ao efeito oxidativo do oxigênio

I bought two and both restart the vacuum pump every 20 minutes so clearly it leaks fresh air back into the container and has to re-vac that out - this means it’s constantly having an air flow through the beans so may as well just leave the lid on without the pumpI would not recommend these to anyone and I want a refund

The media could not be loaded.  Used for two weeks so far and we love it! Very cool design, so easy to operate. The vacuum seal never fails. Battery lasts for 200 cycles!

I used this to store coffee beans and used it 3-4 times a week for about 3 months. The vacuuming function stopped working recently. I reached out to the manufacturer via their website and have not heard back. I didn't expect this thing to last forever, but thought I would get more than a few dozen uses out of it before having to throw it away.The canister itself is decent.

Vacuum storage and freezing will keep your coffee beans (and other stuff) fresh (almost) forever. This device is super easy to use with indicators for full vacuum and for absent vacuum. Just double tap the power indicator to start vacuum suction which automatically stops when the air has been sucked out and the vacuum indicator lights. It is too early for me to determine durability and how long the vacuum lasts. But so far so good. Forget about these "air tight" containers which do not get rid of the oxygen. I'll follow up after a more lengthy evaluation but this product appears to be well-engineered and effective.
