Great value for the price. I looked at a lot of top side creepers and this does the same thing as the more expensive models.
Pros:
Price
Good range of adjustment / easy adjustment
Stable even when fully extended
Cons:
Screws that hold the padded platform to the frame stripped out - had to replace with larger screws
Doesn't fold flat for storage
If they included larger screws and made it easier to store, it would get 5 stars. I'm going to modify mine so that it can fold for storage.
