Works with Bluetooth on. It smells good and really helps your pet area smell good.
It turns off when I'm away from the house.

Did not fit into PETKIT I just bought - has no clips so put glue strips didn't stick 2 days
Did not fit PETKIT I just bought July 2023 - has no clips as the video shows which was very confusing as it included these sticker strips in the pack which I used and didn't last 3 days. Then I duct tapes it in place and it still fell into the litter and eventually got dumped into the waste bin which clogged it up and sent a red notice to my phone telling me it was full when it was full of the deoderizer that got dumped into the waste bin. It needs to be better explained in the description that it DOES NOT FIT INTO OR WORK IN CERTAIN PETKIT MODELS AND SPECIFY WHICH ONE IT DOES NOT WORK IN PLEASE! I WISH IT WORKED AND WANTED TO KEEP IT AS I TRIED SEVERAL WAYS WHICH ALL FAILED.

Does the job!
My PuraX litter box can have an odor when it gets closer to being emptied but once I purchased this the odor has been eliminated! I appreciate the sleek look of the purifier, it's small enough to blend in with the wall and is super easy to use. I also love that it connects to the PetKit app so its in sync with all the other products I have and lets me know when it's time to refill.

Works Great most of the time!
Unit does a pretty good job most of the time but does seem to decide to just fall off the grid and need to be reconnected to app and litter box! Other than that it does great. With it and the odor unit on litter container it's hard to know that there is a litter box nearby!

Pretty awesome
There's a slot inside the letter box that this freshener sits in. It works perfectly but unfortunately mine came out of the slot during a litter box clean and must have gone into the waste basket and I must have thrown it out in the bag, so i was sad

First one worked great but this one…
Won’t stay connected. Bought to replace the original one that got lost while moving. Original one worked great, was quiet and easy to set up and use. This one I have to reconnect all the time and it tells me the auto function set up fails each time because it’s not connected… I’ve set it up like 20 times now. It works for one spray then disconnects again…might just be a faulty one..

Great for OUTSIDE the litter boxes!
I saw the reviews and was hesitant to purchase this, but since I wasn't buying for inside the litter box, I gave it a chance. It sprays on schedule, smells amazing and keeps the area around the two boxes smelling great. You'd never know I have cats, just a nice smelling house when you open the door.

Don’t buy - waste of money.
Not worth the money. It constantly disconnects from the litter box and says the batteries are dead (4 AA’s) a day or so after you replace them. At first I thought it was because I had it on a schedule to periodically spray, but even when I turned that off & replaced the batteries with brand new ones it was dead within 24 hours. The spray itself smells fantastic - just wish the actual device itself worked. It didn’t fit in the PuraMax2 like it said it would, where you place it it’s supposed to hook on but that’s false. You have to use the stickies and they don’t hold it (which ends up dropping into your litter box). I ended up sticking it to the wall with a command strip, but still. If it actually stayed operational and stayed connected to the box without me home I would give it 100 stars because it’s quiet and does actually smell good. Super disappointed.

You set the schedule to deodorise however unless you’re constantly connected to the Bluetooth / app it won’t work. The light also only comes on if you turn it on using the app. It needs to be automatic without constant connection to the app. Maybe the until it faulty but not a great experience sadly. All my other cat products are Petkit and work perfect

It’s an automatic air freshener that you have to keep refilling often . Did do any noticeable improvement
