DiverseyPower Screen PWR-4O-10 Anti-Splash Urinal Screen by Ekcos, 30 Day Protection, for Cleaner Bathroom Floors, 8x7-Inch, Orange, Tropical, Pack of 10

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).

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.

CUMPLEN SU FUNCIÓN, SIN EMBARGO NO TIENEN UN AROMA TAN FUERTE COMO EL ESTILO EN "V", POR LO QUE RECOMIENDO MÁS EL OTRO ESTILO.

They work, but not for very long. They appear to keep the odor down quite a bit, but the scent does not last very long, maybe 10-15 days is what I have noticed.

Have been working well so far and pleasant scent
