The Mensa Brain Trainer and Sudoku have proved so successful with the public that all our stocks have now sold out!

The handheld electronic gifts were only launched this autumn, but have been such a hit that every one we had has been snapped up. There may still be a few out there in Debenhams, M&S or John Lewis stores, or available from some online retailers, and we expect to have further stocks early in the New Year.

Other items from the Best in Test range - including the Calendar Challenger and Classic Orb - are still available from the Mensa Shop

Thank you for the superb feedback we have received so far regarding the 'Best in Test' range, and don't forget that your suggestions for new additions to the range are very welcome via productideas@wowstuff.co.uk
