## Description

Review: Great after-sale service - Good product. Only just started using it, but so far seems to be working as expected. I initially had problems installing the software. So I contacted the Viisan technical support team - from the same site I downloaded the software from. They were absolutely amazing. Responded within a few hours, first offered a list of steps I should try myself to resolve that particular issue; when this failed, they offered to fix the problem themselves, accessing my computer remotely, which they duly did and solved the problem successfully. Thank you, Viisan, for such a superb, hands-on, after-sale customer service!
Review: Supplied with EU power brick - Second review, first one rejected. Scanner was supplied with an EU power brick. This is illegal in the UK. After spending another £15 on a replacement power supply the scanner now works. The software is OK but the lights on the scanner make it very difficult to avoid glare from the document. So £30 pounds later for 2 separate LED lights I now have a scanner that give acceptable results. I could have achieved this with a whole boat load of other scanners for less money and far less hassle.
