DiverseyEkcos PWR-4O-10 Powerscreen Anti-Splash Urinal Screen, 30 Day Protection for Cleaner Bathroom Floors & Odor Deodorizer, Tropical Scent, Orange (2 Packs of 5) 10-Screens

I use these in High traffic Porta-Potties. I've tried two scents so far (of this particular brand); the "Fresh" Blue and the "Tropical Fruit" Orange. Didn't care for the Blue, but LOVE the Orange. Smells like strong Tangerines. So far they have been in 3 weeks and are still giving off enough scent to not change out. 4, maybe 5 weeks will be it.I'm in the SW US where temps are over 100 during the day and humidity is low. I suspect the scent would be stronger in higher humidity climates.These units are serviced every other day, so these screens are spray rinsed, top & bottom, each service.In addition to the scent, they are a big help in reducing "splash" out, which is a big plus "in a Porta-Pottie". They also prevent the urinal from plugging when someone puts TP in it. In fact using these cut the number of units with TP in the urinal notably. (people put TP in the urinal thinking it will eliminate the smell... it doesn't.)TIP: if you ever use a Porta-pottie and the urinal smells when the rest of the unit is in decent condition, MOVE TO ANOTHER UNIT! It means "that urinal" was recently used and hasn't fully drained and/or the chem vapors in the waste tank hasn't propagated up to neutralize the odor yet. Putting TP in the urinal only saturates the TP and the smell never goes away, (until its properly serviced).Diversey power screen 30 Day Premium Anti-Splash Urinal Screen and Deodorizer - Fits Most Top Urinal Brands, 8" x 7" Orange/Tropical (10 Pack)

I was definitely a skeptic, but, I will say there are far fewer drips down the urinals and none on the floors since I've placed these! The scent is not overpowering in my opinion and seem to actually absorb the typical urinal scent. They have been in place for a month and still have a bit of fresh scent to them. Will keep buying!

Smells great. I actually bought these for my truck as air fresheners. Just hide one under the Seat and it lasts a good while. Everyone who got in my truck mentioned that it smelled great. No one is none the wiser.

Works fine keeping the splash down. I would have liked a little more smell from it. I work in a shop of all guys and sometimes the urinals need a little extra clean smell to them!

I know that the aroma is really pleasant. not sure of the longevity, cause I just received them. but I have to admit, the price was great.

Great design and long time use. I have tried other urinal inserts, but these have become my go to in my cleaning business!

These really keep odors down and are a pleasure to pee on.

Very strong smell. Which is the exact purpose of buying these. But its almost overwhelming in a small bathroom for the first day or so
