I intially ordered two lesser known brand battery's from this company, when they arrive, very fast delivery, I found when i put them into my new Lumix TZ8 Camara, a received a warning message ""( UNable to use this battery may damage your camara). Its to do with what firmware is installed on the TZ8.
I contacted the company, and they told me to send battery's back, which i did, and they sent me Panasonics own battery. Free Postage, no extra charges.
Very impressed with thier Customar Care. Would recommened them.
