This gets good marks b/c it was cheap and with kettlebells you really don't expect much. The styling can change however as mine had a glossy finish and how they seem to be more rough iron.
These are a necessity for earlier Echo bikes. I'm giving it a 1 on value however as they should include these in the purchase and not make you buy them separate!
Monitor lacks the detail and insight of the PM5 but the tower itself is in the same level of build as concept 2. Id still prob go with concept 2 if going anywhere outside of a home gym.
