If you’re going to use this fairly often and need this level of accuracy, then it’s a great product. It’s a bit pricy, but it’s a good and well-known brand and looks to be of good quality. I like the amount of adapters and that it has a carrying case with a window, so you don’t have to label it for grabbing quickly. I like that it’s digital, that level of accuracy is paramount to “moving to the next level” in most hands-on jobs/tasks/hobbies. You can unequivocally know the precise compression measurement, rather than just looking at odd gradations on an analog dial. It’s a food processor versus a knife and cutting board. It’s a paint roller versus a sprayer, a horse and carriage versus a Mercedes R350. Do you NEED this? Not at all. Do you “NEED” this? Hell yeah ;)
I've used this a couple of times and it works very well. Being able to record and store compression numbers for up to 12 cylinders is very helpful. I have a four cylinder so I'm able to run three test series and keep the data on all three runs available until I have time to record them.
Very complete kit love the fact u can save and look back at all the cylinders also comes with the air bold witch it nice and all the adapters u will need they make very nice stuff
