1 of the bulbs were broke.

Works great!

One works, but I purchased and need two. Second bulb’s base, the part that screws into the socket, disconnected from the bulb after it was half screwed in. Had to use a special tool to get it out. With a new batch of baby chicks arriving, I had to go to the store a purchase a replacement. But things happen. What ticks me off most is Amazon’s return window. Fine if you use a product immediately and find a defect. But what if you are planning in advance for something, like oh say maybe, 35 baby chicks being delivered in below freezing weather? No recourse with Amazon and no comms with seller. I’m a planner and this isn’t the first time the big A has stuck me with defective merchandise that I purchased in advance. From now on, if planning for chicks, a new dog, or putting in an irrigation system, or any of the dozens of projects ahead of me, I will be sourcing my product locally. I do not recommend this product due to poor manufacturing and quality.

I have bought a few packs of heat emitters from this company and they are constantly going out. It’s a huge problem because the lives of my snakes depend on this heat. I just received a new package of two and one of them is ineffective. Does not work. I have a bunch of random defective heat emitters in my basement. These were supposed to be the most reliable form of heat. I have better luck with a light bulb.

This product works great at a fraction of the price of the name brands. I have this bulb hooked on a dimmer switch which allows me complete control of the heat output. I’m glad I found these before spending a lot of money elsewhere

As for longevity I don’t know yet since this is the first time we purchased them. We have only used them for about a month.

Great product! Fast shipment! Durable product! Must have for Beareded Dragon owners!

So far seems to be working great. Good value for little money

I needed heaters for a small greenhouse in my garage but everything else was too powerful and potentially dangerous. These fit the bill. Low profile and work as I expected. The surface gets hot and you might not know they are on unless you have them in an circuit that has an indicator light, so be careful before you touch them. I would also recommend using them in a porcelain base socket for added safety.

Good longevity best I have found was recommended by my hedgehog breeder
