So frankly speaking I ordered this for myself as i had prolong hours of typing and working on laptop. So indeed this is a saver for your spine. I feel it's slightly more elevated than you would want it to be but it does have a way to adjust the height.
A suggestion would be - If you want more relaxed experience then you should attach a keyboard that ways you will have a better typing experience (or if you are a gamer)
There is a dedicated surface to let the heat from the laptop vent out.
The con is that its heavy so its not very commute friendly. That ways that is the only downside I see to this product.
