Bought based on the reviews by Chris Heinonen at Reference Home Theater and The Wirecutter. Simple to install, simple to use. Sounds great with high quality audio inputs. Everything you need in the box. Get one.
This is the actual Panasonic brand case. Beautifully designed, quality leather, highly protective and highly functional: you can view the full LCD and shoot with the case on. The inexpensive cases you can find as "by Panasonic" are not the Panasonic brand. The Panasonic LX5 does not come with a wrist strap. The Panasonic case does not include one. I found the Nikon AN-CP19 Replacement Strap to be a good fit.
The PLB-375 is good for only 12 GPS self-tests, which makes it rather costly for sending multiple "I'm here and I'm ok" messages to friends using ACR's 406link service.
Per the product support manual: "This beacon has enough excess battery life to perform 12 GPS self tests over the 5 year life of the battery. Once this GPS testing feature reaches 12 times, the feature will be disabled by internal software."
Example: If you GPS-self test the unit twice before you depart, you have only 10 more "I'm here and I'm ok" messages available. Sending messages to friends using ACR's 406link service costs $60 per year. If the battery replacement service costs $140 (who knows, there is no price listed) the cost of sending 10 "I'm here and I'm ok" messages in one year is about $20 each.
