They fray and unravel after a few washings.
Color: Classic Color
They are exactly what I needed but after a few washings they started to fray and unravel. Also I was looking for black and had to buy the 4 different colors.

Just what I was looking for

Terrible
Color: Fresh Color, Color: Fresh Color
Should be a zero! Would be shocked if these are cotton at all! Feels like polyester, unravels after one wash in a lingerie bag on handwashing—horrible!!!

Great interactive toy
Size: One Size
My overall rating is a 5 stars because our dog absolutely loves the toy! It is a great tug toy and "launching" toy for fetch... Although she doesn't quite grasp the return part of fetching. She'd rather play "case me if you want it back!" I wish I had a better video but didn't think of making one until we were pretty much done playing. But you can see she's been playing hard up until this clip and is still wanting to play more... I'm the one exhausted. The rope part of this toy is what takes playing fetch to another level. Give it a good wind-up and let it fly! The weight of the ball carries it really far and very fast! More than I expected based on other toys one purchased. The first launch almost went over back wall of our yard! Skye didn't mind cause the rope made it easy for her to find it in the ivy. She loves throwing it around up in the air and flinging it around like cats throw their toys around. The ONLY issue is, of course is the durability. This toy is meant to be an interactive toy only. Once you're done playing, put it away if you want it to last. Especially if you have a dog that chews everything. It IS well made and of nice material, but no toy will survive her chewing skills. She'd have the rope chewed off in minutes. So it's up to the owner to keep this toy safe! If your dog isn't a chewer....I envy you and this toy will last a really long time! I would definitely recommend this toy for water or beach play as well. It's a big ball, but the rope and the groves in the ball make it very easy for her to grab. And if you don't want to use the rope to play, it fits into the groves around the ball and hooks into place. But honestly, we will never use that feature, the rope is the best part in my HER opinion! Definitely recommend and I'm going to buy more! I'm not thrilled with the price but everything is expensive these days,and if it's taken care of, it will last a long time.
