We've got two lots coming in from different factories (one is the Diatool blade a second is from a factory we already use that make a blade that looks a similar spec) and we're going to run back to back tests to see if there's any difference.
The difficulty for an end user buying direct via aliexpress or similar outlet is you don't know who you're buying from. Diatools is a trading company, they don't make anything. They buy from factories and resell worldwide. So if something does fail and take your eye out you're on your own. That's the downside.
The upside is you're paying cost +100% with no import duty, no VAT, very small shipping costs and no importer markup.
Companies like us do exactly what Diatools does, but in the
UK. We buy direct from the manufacturer of the blade and import it. We need to make a margin that covers a number of costs that Diatools wouldn't pay. Corporation tax, import duty, public liability and product liability insurance (if the blade does take your eye out you can sue us and we're insured) then there's our profit.
That's the reality.
The world (or how we shop) is changing. You see on the news every night about the abandoned state of the high street, people simply no longer want to pay high street prices.
eBay and Amazon has wholly embraced Chinese wholesalers and both platforms have now become like the wild west. See this article specifically about Amazon's struggle.

eBay is suffering the same issue.
Aliexpress is eBay/Amazon but based in China.
It will be interesting to see how we adjust over the next decade as a nation.
Does it effect us? Well to a small degree, but the number of people willing to buy direct is so small (as a percentage of our customer base) that's it not a problem.
The other thing I often chuckle about is the conversations about products being manufactured elsewhere (in Europe etc). I've stood in the Chinese factories that make Dewalt and Bosch blades in the millions along with every other brand name you'd care think of . We even stumbled across the Marcrist factory quite by accident and once they discovered we were from the
UK we were politely told they wouldn't supply us due to their arrangements with Marcrist.
China is the worlds factory, despite Trumps best efforts to mess it up it's still that way.
As long as you understand about what and who you're buying from that's all that matters.
