works well
I was skeptical about this product but thought I'd give it a try. I've had it for a couple months now. It is extremely powerful and, while the smell is strong, it is not offensive or artificial like other air fresheners can be. It's not noticeable as an air freshener i.e. it doesn't have a classic vanilla, coconut, citrus, or floral smell. It is very strong so I don't open it all the way. In fact all I did for the first few weeks was loosen the cap slightly. At this point I have the cap unscrewed but covering the whole top. I use it to freshen two small rooms in the entryway for my house. I have two dogs that frequent the area, cooking smells, compost as well as other strong smelling organics make there way through regularly. The Ona Block does a good job neutralizing the odors as opposed to covering them up. The air seems fresh. As always, keeping clean and regular fresh air exchange really helps odor control the most, way beyond any of these types of products. This just helps keep things neutral in the mean time. Worth it!

What Smell?
Awesome. Better than their liquid form. Smells like the dentist's office though and that is not a good thing, but better than what I was getting rid of. I opened and left the lid ajar, would take it off all the way if I needed a boost of control. It will eliminate smoke odors. It lasted 5 weeks, though in the last week the scent seemed gone my odors were still being controlled. At the price and long term effectiveness it is a bargain. I will be ordering the block again but maybe try a different scent.

Little jar of fresh breeze
This stuff works great! Especially in a confined environment such as a garage. If you plan on using outside its useless. If you have "stinky roses" then this will definitely help. However, You have to know the terpene profile of the plant. This gel has the interesting ability to completely mask or enhance odors depending on the plant profile. So it's critical that you know your lady's. Also the scent will be picked up by the buds so don't keep it next to growing plants. If your in a pinch give it a try it can't hurt.

Great stuff
This product is great. It is very strong at first. I like to move it around when I first get them to completely de-odor my car (one night in the car removes everything), closet, under kitchen sink, sump pump room. family members cars etc. then I move it to its final resting place where I intended it to go. I recommend buying a second one 3 or so weeks later and replacing the older one with the new one and moving the old one to a area that does not need as much odor control. It seems to make them last longer if you close them completely every once and a while and let them sit for a couple hours or a day closed. When they get really old put back on the cover and maybe save them. or move them to small areas like the trunk of your car, gym locker or bag, kitty litter room etc. attic, mudrooms, basements. I have also put some of those crystals that hold water that you can put in potted plants, in the ona block and I think it made it last longer.

Wonderful Product!
Some reviewers complained that it put out too strong a scent, so I decided to try just a 6 oz container, This product works so well, I decided to try the 32 oz. gel. From then on I have been hooked on the gel. But for either one, the scent is not strong at all....unless you actually stick your nose into it. But I realize that some people can be hyper sensitive to certain smells. Personally, my wife and I think that it smells pretty nice actually, and not strong at all. But both products certainly do the job when it comes to strong and pungent odors! Absolutely amazing stuff!

Shipping and packaging were all great, no issue
Shipping and packaging were all great, no issue. I've never used this product before so all I knew to expect is from what I'd read on reviews.. The smell is great, nice, and clean without being overpowering. Works well to eliminate odors, specifically I used it in the car as I'm a smoker. My one and only complaint is the duration of how long the product lasts. I'd read the average was about a month give or take. Mine only lasted a bit over two weeks and that was with holes poked in the top. Overall this is a good product and works as advertised. I know now I should buy 2 instead of 1 next time.

Smells begone !
This stuff is no joke! I bought a used car that smelled like Snoop Dog camped out in it for a few weeks. I scraped out a few spoonfuls and put it on a plate on the floor of the car with the heat on high, circulating the air through the cabin to get the cabin filter into the equation. It took a few hours, but did the job well. Don't sit in the car while this is circulating, or your throat and lungs will regret it. Another way it worked well was on dog crap. I have two large dogs. After cleaning up the mine field that is my lawn after a few weeks, I threw everything into the trash can. It was hot out, and trash collection wasn't for a few days. I scraped a few spoonfuls right into the trash can and it Ona did an excellent job of neutralizing the smell.

Works well, sometimes TOO well
I have mixed feelings about this product, but I have to acknowledge that it does its job as intended. I bought it for a fairly small office so that I can vape without stinking up the place. In close quarters with the lid completely off, it's too strong and the scent is definitely noticeable. It smells like a mix of citrus and some unidentified industrial cleaning product, slightly reminiscent of a urinal cake. Resting the lid over a portion of the opening makes it less overpowering, but then I get concerned that it's not eliminating the odor of my vape. To reach a happy medium, I periodically remove the lid and gently wave it around the room like some kind of shaman performing a room cleansing ceremony. That seems to work well.

Idéal dans les WC ou dans des endroits où il faut enlever les odeurs persistantes, ce produit est parfait, pour accentuer l’efficacité, je l’ai gratté avec une fourchette dans une soucoupe , la destruction d’odeur est plus rapide

The best! Had read about it in passing and decided to try one out after using many odour fighters. Yes, I admit the price gave me pause, but it has proven to be the very best at neutralising odours. And so very easy. Just peel the cover back and let it do its job. And so portable, you can do numerous areas so easily. I I have found it to be very effective and super long-lasting. The odour of the item itself is a bit medicinal, and not intrusive, and the jar has a decorative top. I can tell you I would definitively buy it again, and recommend to anyone n matter what size area you have to tackle..

There was a dead animal in my flat roof which neither I or the pest control man could reach to remove (wirhout taking part of the roof off or the ceiling down). The smell was the most awful thing ever, it was permeating the whole rear of the house and was strongest in my sons bedroom. He recommended this product to neutralise the smell, after reassuring me that the dead rodent wouldnt be a risk to our health. I brought one for the kitchen and one for his bedroom. After 12 hours I didn't notice much difference, but 24 hours later the smell is almost gone. Amazing stuff. I've brought another one in Apple Crumble for my son's ensuite bathroom (there isn't a dead animal smell in there, but I'm hoping it will get rid of the sweaty sock and gym gear odour)! Its well worth the price tag and is easy to use. Small but powerful and without the chemical smell associated with some odour neutralisers.
