I recently got a Habitrail Ovo adventure pack which has some tubes and a den unit and a transport unit.
First of all for all of you who have suffered through the half tubes with the annoying attatchy things which take about an hour to get on the Ovo tubes are amazing. They are halfed so are easy to clean but the lock connectors are amazing. So simple to use and extremely sturdy.
I am in no way reccomending getting the Ovo at all as a main cage. Because even with loads of round main units it is still completely rubbish but the tubes are really good!
I am saying this because I know a lot of you oppose the Ovo and with good reason but if you are looking for some tubes or an add-on to a bin or another cage I would reccomend these highly!
Thanks
