Probably one of the few science fictions I have read and liked.
The writer has done awesome.
Though the book has certain flare and humor in it, the non-science people might not like for the simple reason reason that they won't understand some of the descriptions of the rover or Hab provided. Also description of Mike's plans to survive after each hurdle would be a bit tough to comprehend. And in most part of the story that is what Mike has done,
1. Plan how can I survive this.
2. Execute the plan.
3. Make a new plan, since the previous one got screwed.

I though, loved the book. The descriptions given were so vivid and plain and the excitement building with each mission completion (or failure) was simply superb. The book though has certain elements which can't be done, but then no story is perfect.
The writer has definitely done his homework on the Mars Man Mission!
