Sturdy thick thread!
The polyester thread was nice, thick and sturdy - no breakage! It worked great with a heavy duty machine needle (100/18). It required my sewing machine tension set at level 7 which made a lovely zigzag finishing stitch on the perimeter of the fabric I purchased to make a gray waterproof canopy replacement cover for my outdoor swing! Would have liked a gray colored thread but the black thread made a pretty contrast. Was well worth the cost!

Did it's job
Thread color was exactly as it stated it was when I received it. Thread was packaged very nicely and easy to start using. Seems to be heavy duty worked perfectly for the project I was working on. Would purchase it again.

great heavy duty thread!
Absolutely no complaints. I'm using this thread to stitch up empty cat food bags into reusable grocery bags for the local food bank. Haven't had any way to test the UV resistance thing, but as far as a good quality heavy duty thread is concerned, this is lovely.

Good thread
The power machine was amazing. The thread is perfect. It’s a little bit lighter than I thought it was gonna be, but it’s still good for my heavy cheeky machine.

Great value
It's a good heavy weight thread.I'm using it to sew canvas fabric seat covers for a boat. The size of spool has a lot of thread on it and it's very strong.
