Great Products Review by Heirloom
I have used two of the MarsII 400 and 70x70x160cm tent combo's for over a year with great results. Nice tight stacked nodes. A MII700 might be a slightly better choice and perform better, but still, I'm happy. For the price this combo can't be beat. I am buying 4 more each for Christmas tomorrow during the Christmas Sale.
