Easy to assemble if one is familiar with pneumatic fittings. Where to place wrenches properly to prevent damaging a fittings is required. I encountered no issues what so ever. The instructions are good from my point of view.This can crusher has good quality components for the task in which it is designed for.I was able to crush a large trash container filled completely with un-crushed soda cans. The result was this volume of can being able to put into one trash bag. Excellent for saving space!Now as far as providing compressed air to operate the can crusher.I found this crusher operates very well at a minimum of 80 PSI. Now it does require a compressor with a significant CFM with at least 80+ PSI. Using a small compressor intended just to inflate tires is not recommended.I first used a small 2 gallon Craftsman air compressor. The volume CFM was just not enough to maintain the PSI level needed to operate this can crusher. You crush two or three cans and you have to pause and let the PSI build back up.I then connected the can crusher to a Port Cable 6 gallon compressor. After six to ten cans be rapidly crushed, basically one can per 3 seconds. The compressor PSI & CFM dropped too low to operate the can crusher beyond crushing a dozen or more cans. Having to pause for several minutes to allow the compressor motor and pump recover. Thus the compressor motor having to run constantly. Even then the can crushing process would have to be paused until the PSI could build back up. The can compressor will not crush cans if the PSI drops below 60 PSI. That is not an issue with the can crusher, just an issue with a compressor that does not have CFM capacity at 80+ PSI. So consider if your compressor is up to the task!I advise seriously do note the "Duty Cycle" of the compressor unit supplying air pressure to this can crusher to avoid damaging the compressor.I had to pause the crushing process often with my compressor as the PSI just would drop to low to operate the can crusher. This is not a fault of the can crusher considering what the process requires.I would recommend a large volume compressor of 20 gallon or more or if less volume with a compressor motor & pump rated with a 100% Duty Cycle (continuous run) cycle.So refer to your compressor manual as to the "Duty Cycle" of your compressor motor. My Porter Cable compressor stated the duty cycle was 50% maximum to prevent overheating the compressor. That mean't not running the compressor more than 30 minutes within a one hour period to prevent from overheating the compressor pump and motor.As for this can crusher, it is super when the PSI and appropriate CFM is available !It works quickly with little to no real effort on your behalf.I am a retired industrial electrician/instrumentation tech. Operating and hearing the rapid crushing cans brought memories of production line operators making meaningful progress forward.

Simple to assemble, setup was quick. Crushing action is quick, and it crushes cans very thin. Much more enjoyable than a manual lever style crusher. I like that you can fit a pounder style can into it, which was a factor of my decision on this crusher. I’d recommend this crusher.

I've been using a low cost hand operated crusher for decades. Our family tends to drink a fair amount of pop in cans, and the cans accumulate because no one wants to take the time and effort to crush them. I bought this air actuated can crusher on a whim. I am very pleased with the purchase. It works incredibly well and is much quicker and easier to use than the manual operated style. All cans crushed uniformly whether they were partially dented or undamaged. I crushed in excess of 100 cans in under 15 minutes. I will say it uses a fair amount of air, I had it connected to a 5 gallon portable compressor and it pretty much ran nonstop the entire time I used it. I will likely end up installing it in a more permanent location in my garage and use my larger 60 gal. compressor to alleviate having to listen to the compressor drone the entire time while it id in use. The quick disconnect fitting supplied works, but will also be adding either an elbow fitting or a short whip hose to make it easier to connect disconnect due to very little clearance between the body of the tool and the fitting. Overall it is a great tool and I am very pleased with the purchase.
