anyone use Seachem Ammonia Alerts?

Just wondering if anyone uses Seachem Ammonia Alerts in their discus tanks? I've ordered one from an online store along with some other things I needed any just interested to hear other peoples experiences.

Yes they're great Jason. I use them in fry tanks.

They work well but you do need to keep them clean.

Thanks for the feedback, they seem like a really good idea as an early warning system if there is a problem.

Has anyone compared how sensitive they are to the normal drop tests?

After having a recent ammonia spike I think it might be a good idea to get one if they work well?
