its okay. nothing fancy but it works for what it is. the strap is kinda flimsy though so i wouldn't trust it to hang off a stroller, just keep it inside your bag.

It’s okay for what you pay. The netting is a bit thinner than I expected, and it feels a little flimsy when the kids hit a hard shot. Tbh I don't think it'll survive a harsh winter outside so I'll probably take it down in October. Decent if you just need something cheap and fast, but don't expect pro quality.
