Bests & Worsts Reviews from Amazon

VERY upset. I have the unit 3 months.worked well., BUT we use almost continuously so its about 3 mo old now and the UV indicator light is yellow turning red. I called customer service to order replacement bulb and they informed me they no longer sell UV bulbs. NO WAY TO GET ONE. I asked is this due to regulations or other legal or safety issues? they declined to answer.!!! they will for a one time FAVOR ,send me another unit. BUT it will cost me postage to return old unit and a$10 check for their postage to send me another one. I then asked will the new one be the same model--a UV light lasting 3 months because that will mean for $60 original purchase, plus $25 postage there/back Ive bought a DISPOSABLE unit needing to be thrown out. I asked for supervisor but he wasnt available and I got his voicemail. THIS IS UNACCEPTABLE, IMO.
