The tank I received had only 1 year 3 months left. You are not saving anything since a Hydro test is more than the cost of a new bottle. I paid 50% of the price for 20% of the bottle. Customer service said if I didn't like it I could send it back at my cost. Not very nice since I already paid to have someone send it to me. No more ANS purchase where an expiry date is involved.
Nearly Expired
