Incorrect advertising
This is not the item it is advertised to be. It says WA0037 which is the one for my grass trimmer, but it doesn't fit. The WORX company gave me the item number I need so it should fit. The wrapping on the part does not list my model (WG184). So apparently the number on the package is wrong.

Good fit
Great fit. Got the trimmer working again, but the spools were for the older trimmer. Do you have replacements for the new one.

Replaced worn out trimmer spool cap
New spool cap on string trimmer fits perfectly. Took me two years of heavy use to wear out my old spool cap. WORX is great.

Spool Cap Cover #3
To be honest, these are poorly made - I am on my third cover and we were in a drought this year, so it was only used a few times this year. Very disappointing how quickly it is compromised structurally, I cannot give it my recommendation as the actual trimmer itself is starting to come apart as well. Overall, it is not a sturdy product...that is my truth.

Nice
It is nice to be able to get quick responses to seemingly trivial things. I was able to quick resume use of my trimmer.

Oops to big
I thought I was getting the cover for the smaller spools but oops I didn’t. So now you know I don’t know how to match this stuff up. But I did make a suggestion about putting the cap and spools together and I saw that you did that. What a grate thing to do for us older women who have no ideal how to order this stuff. So thank you for doing that.

Spool cover
I bought these spool covers because my cover broke They were delivered in a reasonable amount of time. They were reasonable priced. I was so happy to get them so I could finish weed eating at my elderly parents home.

Tough!
This replaces the original cap on my string trimmer after 5 years of almost weekly service! If this one lasts 5 years, well that's just amazing. Great parts for great products.
