I've used this a few times with excellent results, although I encountered a couple of minor issues. The on/off trigger switch broke the first time, and I'm not sure if it was due to an impact or if it broke on its own. Since it's continuously on now, I simply plug it in when needed and unplug it when not in use. Additionally, it doesn't vibrate immediately; you need to give it a bump to initiate the vibration. Once you're aware of this, operating it becomes straightforward.

Despite these issues, I recommend it because it does the job effectively, and the price was fantastic. During my initial use on a 5-yard pour, I was pleased with the results when I removed the forms later. While I could have been a bit more aggressive with it, overall, there were few voids. I'm confident it penetrated all the reinforcement steel in the form.
