Review on UVB11 Disinfection Filter Replacements by iSpring by Rose Sanchez

I bought this product on July 19th. With delivery, installation, finally I installed it around the beginning of August. It burned down on November 8th. Ispring claims to run 8000 hours = 333 days. Well 90 days is more than enough to burn it down. I will not buy a new light bulb every 3 months. FORGET IT. I have four ISPRING reverse osmosis filters, but this is absolutely unacceptable. This lightbulb is useless. Don't waste your money on it. I would rather buy a Chinese copy of this lamp at 1/4 the price. It won't last, that's for sure.
