    The thicker o-ring on my probe broke when I was changing batteries. Price and shipping was reasonable and arrived in a few days, saved me having to try and find the correct ones otherwise. In hindsight I should have ordered a second set for spares.

    Worked like a charm. Looked locally for the right size O-rings and failed.

    Hopefully new rings will prevent water leaking into battery compartment
