I don't know how it works, but it works. Celery lasts forever whether you want it to or not. Keeps veggies crisp and fresh. Frankly, it's weird.

So far so good. Very easy to use but I haven't had it long enough to know I it works.

I just received a replacement for this product which I ordered but it was not delivered. I really appreciated the ease of getting the replacement product from the manufacturer.

My produce last nearly four times as long with the Blue Apples than without. I have told all my family, friends to purchase these and they all also rave about them. I am still using my big apples several moves and years later. Important to change filters or you will not see expected results

I was skeptical at first but these really work. My boyfriend and I buy most of our groceries at Costco and the fruits and veggies almost
always go bad before we can finish it all. But its still cheaper than buying it from other supermarkets so"¦Well I took a chance on this
product and I've been pleasant surprised with how well it works.
It extends the longevity of your produce so that it won't spoil and go in the trash. Its less wasteful and better for the environment"¦something
I've been trying to be more conscious about. Cutting down on plastic/paper waste was pretty easy with mesh produce bags and
sponge cloths like this instead of paper towels. But food waste has been more difficult to tackle until I found these!
You just place it in the fridge or wherever you keep your produce. Theres a packet inside the blue apple that absorbs ethylene gas, the things
that causes your food to ripen. Most of our fruits go into the humidity control drawer in the fridge so that's where we have ours.
Before we got these, our produce would go bad so quickly (sometimes in 3-4 days) but now that can easily last 1-2 weeks. Lettuce, apples, bananas,
onions, ginger, it works for everything. You can tell it's fresher by just looking at it. They don't get soggy anymore.
It hasn't been 3 months yet so I haven't had to replace them yet but it sounds easy enough. You just twist open the plastic container and replace
the packet. The product comes with 8 refills so that should last me at least a year. Not sure if I can buy just the refills themselves but
I'll figure that out when I have to.
I would highly recommend it if you're experiencing the same problem that I was having. The effect is noticeable, and you'll save money from not
having to buy as much groceries. Yes the product itself isn't cheap at $20 for 2 but it won't take long for you to get that money back from your produce.
PS- The Bluapple is made in the US, not China!
