POOR - BUT I HAVE NOT REPORTED TO TRADING STANDARDS. TO BE FAIR WHEN I E-MAILED ABOUT PROBLEM DOORFIT THANKED ME FOR ALERTING THEM. I PAID RATHER A LOT FOR A DOORBELL PUSH - CHEAPER ON SOME OTHER SITES. CLEARLY STATED ILLUMINATED BUT ON ARRIVAL IT WAS NOT (SO i MAY AS WELL HAVE SAVED AND GOT A NON-LIT VERSION). THE BUBBLE PACK HAD A LABEL SAYING ILLUMINATED, SO MAY BE SUPPLIER AT FAULT. WHEN I INSTALLED THERE WERE NO INSTRUCTIONS AND THE CONTACTS WERE SO POORLY DESIGNED IT WAS NOT REALLY POSSIBLE TO INSERT A WIRE AND TIGHTEN - SO A SOLDERING JOB - 5 MINS BECAME AN HOUR !!
