Great...with a couple caveats.
The batteries I ordered for my data logger arrived in short order safe and sound. A couple of things need to be mentioned. The tiny batteries were quite expensive in my opinion, but they work just fine. The shipping department overdid the packaging. The 2 batteries were 1.5" long and about 1/2" wide. The shipping box was 7"x7"x4" full of packing peanuts. A padded shipping envelope would have done the job. I do love my data loggers which have been operating flawlessly for the past 3 years.
