However there is always a risk in each case and it`s still possible for each to sell good or bad stuff too, just like in the high street and on market stalls too.
My understanding is that while the overall quality may vary somewhat, large established western manufacturers and importers generally try to avoid selling stuff that is outright dangerous. In the long term the cost of lawsuits, recalls and reputation damage just aren't worth it
Some buisinesses though, either lack the capability to do due diligence, or are deliberately run on the basis that the business will be long gone by the time their liabilities catch up with them.
And yes, dodgy buisinesses can be found on the high street. This is particularly true with landlords scrambling to keep the units filled in the face of high street decline and business rates that are slow to react to changes in property value but there have always been shops I have regarded as dodgy.
My heuristics for how likely a company is to be dodgy include.
How long have they been established?
Who are their owners?
Do they make it easy to find their legal buisiness name and look up their records?
Does the address listed on those official buisiness records seem to be an actual address of the buisiness?
How much data do they provide about their products?
Do they claim third-party certifications? if so can those claims be verfied?
Do they sell products without an identifiable brand (either their own, or the manufacturer's, I don't really care which)
Sometimes my opinion on buisinesses change, when I first encountered fusebox they struck me as very dubious, but they seem to have cleaned up their act. Their legal buisiness name features prominently on their website. The registered address of said buisiness seems to be an actual operational location rather than a virtual office somewhere and they have gone out and obtained certification of their products from a third party safety lab.
UK electrical installations were a mix of BS1363 and BS546 sockets
And a bunch of proprietary stuff too.
It seems the plug or adaptor needs to be fixed, so these

I presume the idea is if the converter requires a tool to remove, it won't get separated from the applicance, and therefore the user won't be tempted to do dangerous stuff to plug the appliance in.
These
View attachment 338008View attachment 338009 all do the same job, but only one is fused, and non grip the plug firmly
It looks to me like two of the three are fused, though the fuse carrier on the middle one is difficult to see because it's the same colour as the plug body.
The left adapter seems like a shaver adapter, only suitable for very small class 2 loads. In my experiance, these most commonly use 1A BS646 fuses, though I have seen some with BS1362 fuses.
The middle adapter looks like a typical "visitor adapter". Supports multiple plug types which leads to a less than ideal fit. On the positive side, it does appear to be fused, has shutters and makes some attempt to stop mis-plugging. It will provide an earth for stuff with some styles of plug but not others.
The right adapter is what Clive calls a "death-dapter". It lacks a fuse, it also lacks any protection against mis-plugging. I've also seen reports that some of these adapters have very poor construction quality.
The radio came with a USA plug which I don't really want to change.
powerconnections make converter plugs for US plugs. The part number is "ACP" for 2 pin US plugs and "ACP3" for 3 pin US plugs.
