My only concern with buying from China on a site like AliExpress is the returns policy if it arrived faulty, or if it developed a fault.
I have mentioned this in previous posts, but I guess you may not have seen it.
The tent I purchased arrived exactly when promised (next day) Although listed on Ali-Express they had UK stock.
I opened up the package and assembled the tent, but couldn't work out how to fit the end of ONE pole thru the eyelet in the tab, all others fitted, but this one didn't, I tried moving the poles around to see if it was 'handed' and this 'nipple' fitted into a specific tab, but NO! it would not fit anywhere.
Emailed the company and explained the problem (sending them a photo of the 'wrong' nipple alongside a 'correct nipple'). The company said they would send me a replacement by 'Over night express'.
Next day, parcel arrives and I think that's a bit big just for a 'nipple'.
It turned out to be a COMPLETE replacement, poles / tent / flysheet / Guys / Footprint / pegs - the whole caboodle.
Emailed the company and asked them how they would like me to return the original tent to be told "very sorry for the inconvenience, please keep it free of charge with our thanks".
I sourced a bag (5 pieces) of nipples froma seller on Ebay at a cost of " a couple of pounds", 2 minute job to replace the nipple and then 2-spares in each of the 'peg-bags' (Just in case I ever need one) and I ended up with 2 complete tents for £75 + £2.
I have no hesitation in recommending Chinese companies for their service levels.
The difference between the nipples.
