Chris T believes he had about a 10% failure rate of the 123 dizzy, including failures of items received as replacements for failures. He also says that the manufacturer is difficult to deal with and that he has tried other makes which seem no better.
The mainstream suppliers like CAS (whom Bazessex used) or Franssen (whom I used) will have sold more and have better data and will probably get a better response from the manufacturer – being local.
