Excellent quality, very useful

I ordered the Vac100 with this 3-gallon chamber and I was very impressed with the speedy delivery, packaging and overall quality of the products. The chamber is easy to use and built well. I can see this (as well as the Vac 100 main unit) lasting a very long time. I'm very happy with my purchase. I would recommend the Vac 100 highly as well.

Awesome accessory

This 3 gallon accessory is truly amazing. I do lots of freeze drying and with this I can seal my food in the jars faster. I can seal multiple jars a once. Love it.

Thanks for the feedback and kind review! Enjoy.

best Turkey I ever smoked

We made up a brine and pulled a vacuum on a 12# turkey for 24 hours. The Chamber held the vacuum while sitting in the bottom of my refrigerator. Smoked it low and slow and it was the best. Would love to explore more brine recipes for roast and steaks. Well worth the money

Sounds like a happy thanksgiving is coming up for your family! Glad to hear the unit is serving you well. Thanks for the feedback.

Everyone who owns a Vac100 needs a JVR chamber sealer

Today I was dry sealing quart wide mouth jars four at a time. The seals pull down extremely well, very impressed with the job it does. Haven’t began to explore all its capabilities yet.

Mason jars are a great start to using this accessory. Feel free to try out some meat marination or using it as a sous vide bath for some steak perfection! Thanks for the kind review!

Awesome attachment

First let me apologize for not leaving a review on the Vac 100. It is the best vacuum sealer in its class.
The Vac100, if left unchecked, will literally vacuum shatter traditional store brand marinade containers. This one is solid as it gets. I have marinated 10lbs of meat for kebabs with no problem. Rib racks vertically and look forward to trying mason jars. I may look for an deeper pot with the same diameter opening for marinating longer rib racks. If you don’t have this, get it.

Thanks for the amazing feedback We are truly proud of this unit in every way. Nice to hear some feedback on the 3 GALLON chamber. Enjoy your chamber accessory and. your Vac100!
