I've also had the X1 since October. No problems after upgrading to version 3.0. It's a fairly early serial number, so I think that if you get a good one, it's a good one, but there do seem to be some lemons. It's a small company; maybe one guy having a bad hair day can make a difference.
By the way, mine's for sale. X1HD, expanded pattern memory, harmonizer installed, 6-switch footpedal.
