Check the batteries in your gear often.
I failed to do that and this past week found out that one of the AAA Rayovac batteries in my Kestrel leaked and ruined the board. I will say that dealing with the customer service departments from both companies has been GTG. Even though Nielsen Kellerman doesn't cover battery leakage in their warranty, they offered to sell me another one at a greatly reduced cost. Before I went that route though I decided to try Rayovac's CS department to see what could be done on their end since it was their battery. Luckily since the batteries hadn't expired and it ruined the device I could send it in with the batteries and receive a refund. I still have to ship it to Rayovac but it looks promising that they'll cover the cost of a new Kestrel.
