Review: Good deal - Bought it for my nephew and he loves it. Purchased this particular one for the price, kind of in the middle. It arrived in perfect condition.
Review: Don't waste your money! - Every time kids used it, it was tangled within the first 5 minutes, and then took an hour or two to untangle. Very frustrating. I even tried cutting off every other string, so there would be fewer strings to get tangled, but everything still got tangled within a few minutes. Poorly designed, so it is essentially worthless. Don't waste your money!

### ⭐ Cheaply made.
*by A***R on September 1, 2018*

Garbage product!!!!! What a waste. It came partially damaged and after using it once it completely fell apart. I contacted the seller and said it had passed the 30 day return. I guess it’s only supposed to work for one month!!!! Do not buy this.
