I got this to use as a "vacation home" for my guinea pigs when I am away from home and have to take them with me. I specifically bought the Plus version since it came with a lid, but I almost wish I would have just bought the regular one and got a lid separately. The Plus version also comes with a divider, which I only used once because the ramp is too steep and slippery for my pigs and it cuts into the amount of usable space for the pigs to lounge in. More space is ALWAYS better for piggies and this is just fine to keep them in for a few days provided they get plenty of exercise outside of the cage. However, this should not be used as a primary home for pigs because it is much too small.
