Service is a good idea as it is new to you and you don't really know its history. Occasionally, the Air2 will begin to leak a little, not ucommonly, a bit after service. You can detune it and stop the flow with an appropriately sized Allen wrench down the nipple channel to engage an Allen screw. I turn it about an eighth of a turn at a time until it quits leaking. It continues to breathe just fine. A service tech taught me this more than 10 years ago, has come in very handy.Received today...in great shape as advertised. Will need to rebuild air2 as it bleeds alittle when inflated.
Thanks again! Excited to give it a try....now I just need a medium for my wife lol
