Apologies. Looks like I was getting my driver versions and installer versions mixed up! I recently installed the driver set from Hitec site and not had any issues as yet but I'll have to confirm what driver version I'm on. Not aware of any better method. You could use the handset in PC direct mode but would still need drivers to assign the com ports for the connection.

Bit confused. If the prolific driver is v10518, what driver is being updated from v3.3 to v3.6?

My [removed word] can be replace with "very annoyed"!

Absolutely no intention to bait! Naturally your [removed word] as any one of us would be too. It was just meant as a curious question based on what your supplier was saying and the reluctance to replace it. Honest!

But - and just playing devils advocate here as I thoroughly sympathise - wouldn't that only apply if the item was faulty or misrepresented? What's the situation if Takahashi themselves say that it's within acceptable manufacturing tolerances?

Might be clutching at straws but when and how did you buy the scope? From what I've read it, if it was an online transaction then distance selling regs say you have 14 days to tell them you want to return goods even if it's not faulty and no obligation to provide a reason for returning it. Otherwise it would be dependent on the suppliers good will return policy or item is faulty or doesn't do what it is supposed to do - which seems to be in dispute. https://www.gov.uk/accepting-returns-and-giving-refunds If you're not eligible for a refund I would be tempted to have Tak re-certify it. They might find and correct something when taking a closer look at it.
