ONGROK Glass Storage Jar (800ml/2oz) with Vacuum Pump Technology, Air Proof Containers to Preserve Smell and Aroma

I read reviews saying it wond hold more than a few hours. I didn't read directions but other reviews say to pump it 30 times. So I did just that and 24hrs later it's still air tight.

The container itself is decent quality and it is a good size, but the lid does not stay sealed properly. It will begin to leak after only a few minutes of being sealed. I would not recommend this product if you want a good smell-proof container. The lid feels cheap and does not function as well as expected for the price.

I attempted to use this, it looks good and it is easy to use. Lost most of the vacuum within 1-2 days. Will continue to use as a regular jar, I will need to find something else for long term storage.

Bought one just trying to figure out a better way to cure high grade flower and as long as you pump it about 30 times it seems to hold vacuum well .... Compared to regular amber glass mason jars I noticed a huge difference in aroma and taste within two weeks ( I also add a 2 way humidity pack 62%)

I loved the jar and used the stickers and bands to decorate.However, when it was knocked of the table, it shattered into bits and everything inside had minute pieces of glass everywhere and I had to toss it all.

I’ve been using it this for an about 3 months now and the container does keep the smell in but only as long as the suction stays. Now I don’t know if mine is just faulty but the suction will stay for an hour at most and then I would have to reseal it again.

The first few nights I noticed that the jar was releasing air after a few hours of leaving it out.I discovered that if you press the air release button ~40 times (not kidding) it should keep it air tight until you need to open it again

I found cheaper plastic air tight holders in smoke shops that work better than this thing. I can pull this open with minimal effort unlike the plastic ones that actually air seal & can not be brut force open. Find better elsewhere.
