Review of Dryer Balls

I use them in the washer and the dryer. It helps get the tough dirt out by extra agitation. I paid $2.00 for them at a yard sale and it was well worth it.
They also sell them at JYSK which is a poor man's IKEA store.

I have 2 of the blue spikey balls and I use tennis balls as well. I've not had any problems with the quality of the blue balls. They seem to do as advertised, but so do the tennis balls. So which ever is least expensive for you would serve the purpose.

I also use tennis balls, in the dryer, however, when I purchased them and opened the container the chemical smell almost knocked me over, So I put 2 tennis balls and a 1/2 fabric softener sheet into a baggie and zipped it closed for 24 hours and the smell was completely gone.

Don't waste your money. I bought some of these dryer balls and after some time all the spikes broke off. I bought 3 tennis balls and use them every time I use my dryer. Works great!

Instead of wasting money on dryer balls, I use regular tennis balls! They are great for fluffing up towels, quilts, comforters, etc. I've even used ones from the dollar store. They last forever!
