Can't rate the stuff until spring .... otherwise I can only write useless things like "goods arrived on time" or "great canister" .... You are often senselessly urged to rate it early!
I've been using Seatec antifreeze for a number of years. Easy to use and so far always reliable in use. However, the old canister with a spout could also be used universally afterwards and was one more selling point for me.
