I just wanted to put in writting my appreciation for everything your company has done for me recently. The replacement for my 664 mixer arrived today and is working perfectly. Please pass on my thanks to Matt for his patience, expert help and the guidance he has provided despite me phoning, in a panic, from various locations around the world. Thanks to you all for going beyond the call of duty, the level of service has been absolutely fantastic!

These cannot safely be used in devices designed for standard 1.5V AA batteries (Alkaline, NiMH, or Lithium 1.5V). These batteries output a steady 3.6V until they suddenly drop to 2.5V, which can be unpredictable for standard devices (Some devices with voltage regulation might work, but they are not designed for this power input) Check your device manual states "Compatible with 3.6V Li-Ion AA" before using them.
