DO NOT BUY FROM THESE GUYS
Yes, I know I shouldn't have done it, but heh, I like to gamble just a little now and then.
I ordered a battery, after all it's an NZ domain name, and has the official "NZ Post" image at the top, so it must be OK. I traced the package as it wound its way through China, Singapore, Auckland and then through NZ Post to my home. Great service! I thought with optimism.
Only problem is... it didn't fit. After website searches I found the connectors were actually the wrong way around! I contacted their customer support via email, and "Sunny" responded very efficiently saying "Don't worry.. we strive for 100% customer satisfaction etc...". Just return the battery at purchaser's cost and they'll sort it all out. Suffice it to say, but after 24 emails (I'm a sucker for punishment), I was no further ahead. Their aim seems to be to drag things out until you give up, pay them more money, or until it becomes too difficult to get your funds back from paypal.
Now trying to chargeback the item through my credit card. I've also informed NZ Post of the possible unapproved use of their logo on the website.
Also be aware that you are not permitted to ship lithium-ion batteries through normal NZ Post means. You must send it, specially packaged, through a courier company. So while it "cost" them $12 to ship the battery to me. it would cost me over $55 (more than the battery is worth) to ship it back to them... unless of course you lie to NZ Post on the declaration and when they ask you what's in the package.
