I see you've got a beef with asmodus.
I've used a few and passed a few more on to fellow vapers and they're definitely in the reliable category for mods.
Rarely seen issue's from user's on forums over the last five year's and the fact they'd honour a guarantee puts them in an elite category, lol.
All manufacturers will charge to fix or postage which is usually thirty notes plus due to the end destination.
End of the day is these are cheap Chinese electronic devices, no matter how much we covert and are willing to pay. They will fail.
If your mindful of a good return for your outlay then buy from the UK for the maximum guarantee from vendor (best your going to get and still likely to cost you a tenner in postage) or buy a brand with a UK sevice centre (evolv based mods), even better, shout vapesmarter or fyne mods and receive a lifetime of service. Great value in the long run.
Otherwise mods are like £500 banger cars. If it gets you to the next mot without costing too much then it's done well, if the next mot costs more than £400. Bin it and start again.
