Very easy to use.  Simply close and lock on the handle
Attractive blends in nicely with a recently purchased Technivorm Moccamaster Thermal (see my revew)
Easy to clean

Possible Battery life.  I will update this in three months to address the life of the batteries.
A smaller point perhaps, but the retailer did not include the four batteries.

After purchasing the Technivorm 741 drip coffee grinder it made my Tim Horton coffee cans look very bad.  Read a lot of review on this site and found out I knew absolutely nothing about brewing a cup of coffee.  Googles Vacuum cans and found both here and Amazon had good reviews.  Other than the cost of the Beanvac container (nearly $50.00 Canadian each) I thought they would be a great addition to my counter.  I purchased two of them to hold the various beans.

After cleaning the removable container I filled one contain full of beans and the other a combination of four various brands.  I would appreciate any feedback from coffeegeek readers on this subject)  Does having four varieties in zip lock bags spoil the beans...that is do they all mix up?  Should I leave the bags open in the container?

After closing the container and set the lever the canister immediately started to remove the air.  It takes approximately 1 to 2 mintues each time to complete this task.  The container that is full of bean did it in 1 Minutes and the other container took nearly 2 minutes.

One of the biggest concerns I have read about is battery life.  As of this writing there are 30 review on Amazon and one on this site.  This decision to set the settings at either off, 12, 24, 48 hours will be addressed later when the other three containers I have ordered are delivered.

One the bottom of the Beanvac container there is a simple twisting plate to remove the part of the bottom where the batteries are installed.  Next to that is a selection lever showing off, 12, 24, 48.  The off position only will operate when you open the container and reseal it.  It will automatically seal your container.  The 12, 24, and 48 position will check them at those hours and take air out if it is deemed necessary.  I wanted to wait until I could do a test of this with four of the containers set to each setting.  The fifh container is for my wife's ground coffee.  

This should be a good test to determine battery life.  

One thing I have never been able to determine on any reviews was the size of the container.  It is appoximately 8" high and 7" wide from hinge to lever.  I wanted to know this before I purchased to determine space on my counter.  Finding this information after it was already delivered worked out great.  They are not so big as to be overpowering yet they will hold a lb of coffee beans easily.

When the other canisters come I will check out the exact amount of beans and coffee these containers will accept.

I have decided at this time to use regular Duracell batteries instead of the rechargeable ones.  I have found over the years they indeed hold their charge longer.  Should these containers use more battery power than I think is normal I will switch to rechargeable batteries.

I am careful to make sure the top of the removable inner container is clean and there is no dust to hinder the sealing of the unit.

I alternate using one canister each day so the battery life would be used every other day on the "off" cycle"

On the lid of the unit there is a small air value.  When the seal is broken and the container is open the value opens up and lifts up. Upon closing the lid and sealing it down with the side lever the value slowly returns to the lid and is again even with the top.  The instructons say to keep this value clean by cleaning it once every three months or sooner if you think you have a lot of dust etc inside your container.

I have given this product 10's because it has fit my needs completely.  I find the product slightly pricey considering I am purchasing 5 in total, however this way it solves the problem of storing various types of coffee beans.

There are only two factors that could alter my ratings and they will have to be addressed over time.  The battery life and the sealing of the unit.  Since both my present containers are only a week old and both on "off" the battery life is a non issue at this time.  I have read in other reviews that some have found it difficult to seal and they have put small felt stickers between the inner container and the bottom inside of the unit.  This would lift the inner container slightly and make a firm seal.  I have had no problem sealing the lids.  

I have found a company that roasts beans daily not far from my home.  Purchasing their various beans might make the Beanvac container work more frequently when I set the adjustments to 12, 24, and 48.  I will let you know when I update this review.

I am extremely happy about these Beanvac containers...an added bonus is the portability of them.  You can keep them in your cupboard and move them around the container without a concern for any electrical wire.

I am surprised the company does not make an electric model with a larger capacity.  Something that could hold 2 lbs or more of beans.  Perhaps the market for this product is too small to justify.

Excellent packaging and product arrived when they said it would.  Purchased via Amazon from DBOOTH.
