Tested on size models 1/100 (master degree). Well lets keep the models, thanks to its large size. Indeed, it is difficult to see the image, but this stand is about 25cm in length and 1.5cm in height base, and plastic which is made very thick. In short, it is very stable and solid.
Note that I stated, these "Basic Action" pits are for Bandai models, keeping systems are suitable for the Bandai models. Check your model stand recommended in the installation booklet before purchase (action 01 or 02 base ...). It must be possible to adapt a model for non Bandai, but I do not recommend it.
In less: You have to climb the stand (~ mounting 15min), then, the price is a bit high for a stand, but it is worth the money in terms of design and quality.
