Review: Fantastic - I've read reviews that indicate that this is an expensive product? This is not the case, compared with other genuine Olympus products this is the cheapest I could fine. As a genuine product it is as good as the original and makes for an exceptional replacement/spare. The packaging is minimalistic, but it does the job and it was well protected, lets face it I don't need a fancy box, it goes in the bin either way. Delivery was prompt and I'd happily purchase again if I need to.
Review: Good choice - Purchased this as a spare battery for our camera whilst on our holidays. Works good and would recommend this product for others

**Q: Why do people give such different reviews? Some say it is really great while some others say it is rubbish. does it matter who you buy it from?**
A: My camera still displays a low battery warning sign despite replacing the battery but I can't say for sure whether or not it is the battery or the camera is at faulty. I suspect it is the battery but I am reluctant to spend more money on another replacement battery from the same source.

A: It seemed genuine and for me it was perfectly compatible.

### ⭐⭐⭐⭐⭐ Great Item - quick delivery - great price. Amazon - Ridiculous packing - such a waste.
*by F***6 on 23 February 2018*

Great item - delivery as promised - good price - very pleased with the Battery. Ridiculous packing - the Item not much bigger than a Postage Stamp in a Box the size normally associated with a pair of boots - full of packing.... Come on Amazon that is such a waste.
