On January 26, 2010 I bought the Olympus LS-11. This week I received a refund check in full.
The LS-11 in mp3 or wma mode (even when using a 32 gb sdhc card) has a limit of 4 gb recording per session. I bought the unit wanting to do extended length ambient nature recording. According to the chart in the LS-11 users guide it could record over a 1,000 hrs using the 32 gb. sdhc card.
Short story - in continuous mode the unit is limited to one file of 4 gb size. After complaining since February that the unit was not working properly, the head office in Japan stated they would not change the firmware to allow the recorder to fill up the sdhc card. You must press the button after every 4 gb file. I explained that was like buying a car with a 10 gal gasoline tank and then stopping every 10 miles to restart the engine.
After waiting almost 3 months for support to solve the problem, they agreed to refund my money which I then quickly bought the Sony PCM-M10 which does almost exactly what the Olympus LS-11 promised to do but failed to follow through on.
