I am amazed that no one on here has these or one of the other lots of ebay lights. The advice given is always based on the fear that these cheap lights may not be any good, but equally they might be absolutely fine, since no one has them we will never know!!!!
This is a big forum, someone must have some experience?
I have a lot of experience of 'Ebay lights' which is why I advise against them
Leaving aside lights sold outside of the EU, there are basically 3 choices
1st level - Bron, Profoto
2nd level - Bowens, Elinchrom, Lencarta
3rd level - Everything else
The price difference between 1st level and 2nd level is massive, but the price difference between 2nd level and 3rd level is IMO too small to risk buying the 3rd level lights
'Everything else' includes a relatively small number of different manufacturers, normally based in mainland China or Hong Kong. Their businesses are 'export only' i.e. everything they make is made down to a price, not up to a quality standard, and very few people in their own country will buy it, so it goes for export. It's sold unbranded, typically a re-seller arranges with the factory to have its own labels stuck on the case. The re-seller then sells it as their own brand, and some of them even claim to have their own factory

These products are generally easy to recognise because they look exactly the same (apart from the label) as products sold by other sellers (there's a reason for that) and generally, because the seller knows very little about them, they give virtually no detailed info, say little or nothing about the spec and certainly don't tell you what's inside the case, (which is usually either a brittle plastic or a cheap alloy that may not meet EU safety standards).
Now, if you can live with a flash kit made down to a low price (even if it's sold at a high price in this country) and don't care about cheap componants, poor consistency in terms of flash energy and colour temperature and possibly poor safety standards, you might want to think about customer support - if it goes wrong, will the supplier be able to repair it, bearing in mind that they are only re-sellers and may not have the spares, the technical expertise and the facilities that they claim to have? And what if problems occur once they no longer sell that particular model, i.e. once they've found an even cheaper supplier? And what if they go bust?
Most of the ebay sellers of these cheap lights do in fact sell them off of ebay too, but new ebay sellers come and go, some are selling directly from the far east (so the problems you're likely to have when the gear goes wrong will make it uneconomic to return, but at least you'll only be paying twice the factory gate price instead of 4x).
