The only Issue found before I had my business was claiming warranty from various locations, IE- most major companies have authorised distributor networks , these guys are not within that ..they are very good with warranty stuff from what I have heard but you cant simply take it to another shop or seller to have your warranty processed.
If you bought your charger at Auto barn in Melbourne and were on holidays at Bribie I could sort your warranty issues if you had a receipt. If you bought it on ebay then I cant. As the BNE warehouse will not accept it.
Projecta /redarc/ctek are all the same now ..if the item was purchased on ebay it must go back to the seller or directly to the parent company .. If purchased through approved re-sellers then other re-sellers can process the warranties.
Take my comments with a grain of salt or whatever but I just went through a long process for the folding solar panels with projecta in order to guarantee I could support my customers anywhere in Australia.
Just mentioning it , not to pinch sales as I am happy enough with my trade levels but would hate for a member to be caught out not knowing. For many things it does not matter much but with larger elec items that could fail I would make sure to buy from a auth distributor so you have nationwide warranty.
but they are def one of the better on-line sellers that's for sure
