Q: These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
A: 1
Rationale: The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, he gave 1 star to the review considering it extremely poor
Q: Like others, I wondered how the stock Eljer Titan flush handle could cost more than twice as much as this one. Well, I found the answer. First, the lever had to be cut to fit so it wouldn't hit the refill tube...that I was ready for. But then I discovered that there was no way the square rubber gasket would fit into the square hole in the tank, it was way too tight. I ended up putting it in from the inside, and was able to tighten up the plastic nut enough to hold the handle assembly securely. The handle on the old, stock unit, which lasted 15 years, was made of pot-metal, and the little pocket that the lever fits into had split open at the pressure/wear point. The new handle is made of plastic, with a slightly different cam mechanism. I would bet that it won't last nearly as long...time will tell. The bottom line: Spend the extra $10-12 to get a more durable handle that you can install in about 2 minutes with no jury-rigging hassles.
