Things I liked:easy to use, no more leaking probes. Things I would have changed:Nothing. What others should know:Sometimes refill probe's can be finicky to seal. Quick-Disconnect fittings solve
Things I liked:This is so easy to use. Things I would have changed:Nothing. What others should know:Sometimes getting a good seal with the refill probe requires sylicone grease
or backing of the probe just a little. This I experienced with my Sumatra 2500.
Change to quick disconnect fittings and save the hassle.
