“I know that the three-legged bases have been tested as being safer and I do appreciate that this was the base included for our Nuna Pipa. I think any parent would rate any base lower because there is room to question if you installed it right. Yes, the green checks and level indicator are great features BUT it is hard to see if the leg is green once installed. We had to use our phones for light and camera to see if the leg was in the green section. Overall very easy to install using the Latch system. Two clicks and then checking the leg. I also liked how there is an incline feature that you can flip out of the bottom. By using this feature, we were able to get the level in the center on the first try. Overall, great product and I love this brand.”
