When I looked at them, I recalled some had a bed or couch along the straight wall. That meant if you wanted to sit up in bed or with your legs on the couch, your back would be up against the angled wall. For me, that was a deal breaker.
My FoldnRoll is similar but isn't an A-frame. Some similarities are:
Very little storage space. No upper storage. I was able to get around that by hanging wire baskets with over-the-door hooks along the folding wall - but that won't work with the a-frames because the folding walls are the A shape. You could add removable baskets if you are willing to put screws in the walls.
When you close up in the rain, you will get some dripping off the folding walls into the camper. If it stops raining first, you can wipe down the walls. But if it's still raining you may want to lay a tarp or vinyl tablecloth over the bed/couch.
Setup is as easy as you make it. If you bring a lot of stuff, you will have more moving of gear before you can settle in.
You can't access the inside without raising the roof. When the roof is in the down position, it blocks the door from opening. There is a guy on you tube who made a mod to this - he stealth sleeps in his with the roof down.
The bed will be a personal preference. Making up the couch into a bed every night and back into a couch every morning may be annoying. And you will have to find a place to put your bedding during the day. A dedicated bed is easier that way, but you will always have the bed right there. You could add pillows and make it more of a day bed when not sleeping.
Not a lot of space. It's a small trailer. If you have a dog, that makes it that much smaller.
As mentioned above, the A frames lose head room. Go inside and spend some time to make sure that doesn't bother you.
