That is very tempting. Anyone ever bought from aliexpress or have experience with that wing?
I routinely buy from Aliexpress. Very reliable seller, if there is any problem they usually ship you another new unit for free, and they do not even ask that you ship back
the old one.
Aliexpress also comes with its safe payment system, Alipay: it is possibly better than Paypal, and definitely far better than our Italian system Postepay.
I mostly purchase electronics boards (Arduino boards, IMUs, cables, batteries, plugs, displays, sensors, microphones, LED bulbs).
I also buy accessories for my motorbikes and bycicles.
Never purchased scuba equipment, but I am also very tempted by these compact wings.
Of course I would never thrust life-supporting devices, such as a regulator. But for the components of a backpack+wing there are not real dangers in case of malfunctioning, so I am also evaluating this cheap solution for when the travel limitations will be removed (possibly this summer).
Only problem is to order a couple of months in advance, as our Italian customs can take months to clear the shipping, asking you to pay the custom fees.
This does not only affect products coming from China, indeed. It happens from every country outside EU, and particularly for goods coming from US.
