I've poured several pallets of concrete on our house remodel & chose this value model with hopes it would serve the purpose. It does. It's not a problem, I simply dropped it into the concrete a couple times & it always started.
I bought it to do a foundation job and it worked really good. The contractor who was doing the concrete was really happy to use it
This concrete vibrator has done everything I have asked of it. It has a great cord length and has consistently been rough housed without issue on work sites, in rainy and dry weather. It has held up well on about 20+ projects requiring multiple days of use each.
Definitely works great. Got a lot of air bubbles out and I feel comfortable it did the job well.
It was bought to test how it would look on it cement and actually that it is super smooth everything well accommodated I love it
