Update: Rapid response from Rapid! Within an hour of posting this review the team sent out a new, fully checked, replacement Function Generator. I have 'upped' my star rating accordingly. Thanks for your quick action Rapid. --------------------------------------------------------------- Received a faulty item. Contacted customer service immediately then waited another day to get RMA number. Item re-packaged & collected on Thursday 23rd March (should have been received back at Rapid on Friday 24th March). As of today 28th March (pm) I have had no communication whatsoever. I told customer service rep that I was on holiday from 30th March so I will not get a replacement until, at best, 7th April. This was a simple fault to confirm (took me only 10 minutes to discover the fault) so should not take so long for the technical department to verify issue and send replacement unit. Not impressed.
