Excellent price point for what it is. There are no instructions but the diagram was easy enough to figure out.The main problem is the piston overheats with prolonged use and as it heats up, resistance lessens. This means you cannot do an intense 30 minute workout in one sitting, you have to do sets, rest in between, and then do more sets. I'm in no rush, so I can do this, but you should be aware if you buy this.Also, the highest level of resistance doesn't feel like rowing through actual water. It's not particularly challenging. You feel it once you are many reps in, so it still works if you go by volume of strokes. But, again, see above for the overheating issue.Still, if you break the workout into sets of 10 minutes and have maybe 5 minutes of rest time in between, getting 30 minutes of rowing time and 15 minutes of rest still works for me. I'd buy something better for the next machine, but this is a good start.
