I have 5 different Koralia's for sale. They are all around 1 to 1.5 years old, and work.
All, except one of the Koralia-1's, have a direction attachment and guard with it.
I cleaned all of them with vinegar for a couple of days, then water+dechlorinator.
Prices:
Koralia-1's: $15 each, 2 for $25, all 3 for $35. (If wanting less than all 3, please specify if you want the direction attachment)
Koralia-3's: $30 each, 2 for $50.
I am located in Buda, and work in SW Austin. But I am going to the meeting this weekend, so prefer to deliver there.

Koralia-3's:
