Product review (4 stars): Keeping it real...trying to be helpful.
I read some of the reviews of this product where people complain about the quality and how easily these knobs break.

First off, I feel we should all step back and ask ourselves, is there any other option?  Nope, we need THIS Frigidaire knob if we want it to match THIS Frigidaire dryer.  I have a lot of experience with appliances and this may be hard to believe, but the truth is 99% of appliance knobs are made of plastic!

I purchased these knobs to replace someone else's dryer knobs. My advice to them was...
EITHER
Take it easy on the knobs (spending a  tenth of a second to turn the knob more carefully will pay off in the long run).
OR
Get a hot glue gun and fill the hollow back with hot glue to reinforce the plastic sheathe so you can crank that beast of a knob to your hearts desire (or at least until you have to replace the stitch itself from the abuse).

Amazon is probably one of the least expensive places to find these knobs and yes they can break fairly easy but they perform the way they were designed to perform.  Buying them from here or there will not make a difference in how much abuse they can take.

I didn't write this review to be mean and hope it doesn't come off that way.  I just wanted to help those who are reading reviews complaining about how these knobs are made "cheap".  The only reason I gave 4 starts and not 5 is because I cant say I  "love" these knobs. LOL
