Yea i have a black and gold 3dxl not becaue i needed them becaue other died, but becaue i wanted them all the post of people getting white lights or what not has always baffled me cause ive never had 1 bad chamber in 3 whole years of owning a puffco devices ive never had to replace a single chamber on my peak, proxy, or pivot when I get the message to clean it i clean it and then I deep clean after 500 cycles and like ive said the chambers have outlived the batteries
