Here is a link to my refurbish if anyone is intersted. Very, very easy to do, and it made it like day one again.
Dolphin Premier M5 - 4th Season Refurb
Dolphin Premier M5 - 4th Season Refurb
I would not let them dry out with dirt in them.
A little birdy told me....I think his name starts with Patrick!
Is the z5 just the m5 by another name?I'll echo the passion for the Dolphin (Z5 - the online brother). Ours is named Hiro (from Big Hero 6) and he lives up to his name. Love Hiro!!
