I had to use 2 different sizes for my A coil. Also it helps to start partially on the "good" stretch of the fins and gradually work through the bad section. Another tip: try to insert it at the angle. The spacing between fins is not always perfect.

My Heat Pump fins were seriously flattened from being cleaned with a pressure washer. This resulted in poor heat exchange and freezing. I looked at the various products for straightening fins and was skeptical at best. I was absolutely amazed at how well this worked. I thought the comb would quickly wear out or break. It did not. It must be a really tough polymer. I cleaned and straightened every fin on the pump. Many were very deformed. All my fins are straight, the pump works much more efficiently. The comb still looks new. There are many size options. I was using the highest / finest tooth count. Very pleased and completely surprised by the quality of this product. Thanks.

Just does not work. It just wont rake out bent fins on the radiator. The quality of the combs is fine. I will use them as tiny back scratchers or to rake my desktop zen garden. For raking out the dented fins on my AC heat pump, the combs are useless.

Great value. I have seen these for almost the same price for a single one. I did not say Awesome Sauce. That would be stuoid
