This program has been very helpful at calculating costs of projects we are working with right now! It's easy enough so anyone who knows how spreadsheets work could use this product without any training needed (which I appreciate). The interface isn't intuitive but once you get used to using all functions within costminer your usage will become second nature quickly. We have not found anything about CM which would make us dislike their products; everything they do seems like something worth doing well/doing correctly - even if other programs may provide similar features more easily than what was provided by others previously (like Excel).
