I RECENTLY PURCHASED 2 OF THE Neo.Tec  IONIC SMOKE ABSORBING PURIFIERS, MODEL XJ-888 AS A GIFT FOR A FRIEND SO SHE WOULD NOT HAVE TO SMOKE OUTSIDE ALL THE TIME.  WHAT A TOTAL WASTE OF MY MONEY !!!!  FIRST OF ALL, THE AD CLAIMS THAT YOU WILL NOT SMELL THE SMOKE - YA RIGHT.  THE SMOKE GOES RIGHT UP THE STUPID PLASTIC CAP.   IT STATES IT COMES WITH A NIGHT LIGHT - WELL GUESS WHAT - THAT STUPID LIGHT NEVER, EVER GOES OFF !!!!! AND IT IS A BLINDING NEON BLUE !!  THE INSTRUCTION MANUEL INSIDE THE BOX STATES THERE IS A GREEN LIGHT TO LET YOU KNOW IT IS WORKING - THERE IS NO GREEN LIGHT !!!!!!  I CONTACTED THE PERSON I PURCHASED THESE FROM AND WAS TOLD "WE CAN'T HELP IT IF THE MANUEL IS OUTDATED".   OBVIOUSLY THIS IS A DROP SHIPPER THAT HAS NEVER TRIED OR EVEN SEEN THE UNIT IN PERSON !!!!!!!!!!!  I DELIVERED THEM TO MY FRIEND AND WATCHED IT CLOSELY - IT DOES NOT DO WHAT THE AD STATES.  CLEANING IT - OH MY GOSH - WHAT A GROSS THING TO DO.  NEEDLESS TO SAY - SHE TOSSED THEM IN THE TRASH AND I FELT BAD AS I WAS TRYING TO HELP.  SAVE YOUR MONEY PEOPLE - THIS UNIT IS A PIECE OF JUNK !!!!!
