… Can you trust the online ones in your experience please…
Buying online is no different from buying from anywhere else, whenever money changes hands, beware of rogues! When a bloke offers to sell you a Rolex in a pub car-park, it's unlikely to be genuine. A good question to ask is when considering a deal, 'If this goes wrong, how will I get my money back?' Online, Amazon are fairly safe, others less so – you might worry about a vendor in North Korea with no Review history.
Another question is, 'How much will it hurt if this super-cheap bargain fails after I've filled it with data?" The answer might be 'not much', for example I have a digital camera used to take workshop and other utilitarian photographs. Almost as soon as the pictures are taken they're downloaded to my PC. Not much harm would be done if a dirt cheap unbranded memory card failed, and that's what I use. However, when losing photographs would be painful I use another camera – it's fitted with £ branded performance memory.
You might be different but I never store anything of long-term value on USB sticks. They're used for transferring copies, not archiving originals. The main reason I have a few expensive USB sticks is for performance not reliablility, I sometimes boot 'Live' operating systems from USB and find cheap sticks are often sluggish.
Despite it being low-risk in my case, I tend to avoid very cheap sticks because they take you into conman territory. As they feed on greed beware of losing your head if you can't resist a 'bargain'!
