GREAT CUSTOMER SERVICE, but the product? I was given a used Bond patio heater (Item #68149 model HYPH4601-12). It was damaged by the prior owner (It fell over and damaged the supply line to the gas diffuser). I contacted Bond and their customer service personnel were EXCELLENT. The service was very polite, responsive and efficient. This was not warranty work and I expected to pay for the required replacement parts. The cost very reasonable and a replacement burner assembly was delivered to me in 2 days! Unfortunately, I cannot say the same for the product's source manufacturer quality control. The first replacement gas burner assembly sent to me was damaged (ceramic gas diffuser was broken). Customer Service immediately sent me another entire assembly. The second replacement assembly was slightly damaged. (The value control knob was broken, so I used the knob for the first replacement assembly.) Also, some screw holes were not threaded. (I purchased some self-tapping screws to address this problem.) So I now have a functioning patio heater - for a minimal cost. The particular heater is expensive ($500-700 from internet retailers) relative to other patio heaters and is not rated well for heat output. It does look impressive with the open flame in side the quartz glass tube.
