Absolutely Brilliant! My boys love their hammock. It's very robust and I swear it's a TARDIS - all three of them pile in there to sleep and boggle (along with just about anything not nailed down, from plastic balls to ENTIRE newspapers!)
I have two to alternate weekly between for washing and they come out of the machine on a 30' cycle like new. Despite one of my rats being a chewer, they're still going strong four months down the line. Genuine value for money.
