Swear by? I %@#$ing swear by them alright.
I've used Phillips Ecotone CFLs for years but I've had trouble getting them lately so my friendly hydro store guy recommended this pile of shit.
I got it in the mail and fitted it and it worked fine for about 4 hours until the timer switched the lights off. Did not restart the next day so I refit my spare bulb and contact the store. He goes on some rant about how he's never had one come back blah blah..
He tells me to send it back which ends up costing me $20 and sends me out a replacement. The replacement arrived a week later and shit itself in a few hours as well. Never again.
