Review on ⚡️ iPettie Cat Litter Box Odor Genie: Auto On/Off, Odor Eliminator and Deodorizer for All Litter Boxes, Bathrooms, Wardrobes, and Small Areas - 99.9% Dust-Free, 10-Day Battery Life by Wendy Williams

TL;DR Eliminates odor/stagnant air. Doesn't warn of the need to charge, just turns off. When new, one charge lasts for 6 days. Until the 2nd month it takes 4 days. From the 3rd month, a full charge will only last you for ONE day. I have a cat who makes my room very smelly when using her litter box. Even after scooping, a stubborn smell remains that makes the air heavy. I didn't have high hopes for it as it was "cheap". However, it did a great job of cleaning the air in my room and I never noticed how stale the air got even though I always aired my room (I leave the window open for 6-12 hours) during the battery is not discharged. After about 12 hours, give or take, the air became stale again. I would forget this product worked until the smell returned. But that's the only plus. Now for the cons: I bought it in October 2020 and didn't use it until mid-November. I never "reached" the full 10 days as advertised, mine only lasted about 6 days before needing a recharge. And mine never flashed a red light to indicate the battery was dead as advertised. It just turned off and I didn't know if I should charge it until I finally noticed I didn't see the blinking blue light for a while and/or the air had stale again. In mid-February 2021 the battery died and I was only able to use it for about four days before I had to recharge it. Well, as of March 1, 2021, I can only release ONE day with a full charge. And I never plugged it in to charge all day. It took about 4 hours to charge and when the light stopped flashing (fully charged) I unplugged it and used it again. I was about to buy a new one but the price went up and I realized that if I were to buy another one I could just buy an air purifier for the same price (buy the second plus the cost of the first). And if I stick with it, I'll probably need more than 3 times every few months.
