I love the idea of a sandbag and was excited to receive it. It makes a huge difference when it comes to noise levels, and is invaluable for that reason alone. However I don't use it as often as I imagined I would as it is challenging to get the block nestled into the sandbag. I found there was a learning curve when it comes to keeping my work and the bench block centered on the sweet spot of the sandbag in order to prevent movement. I think if I had a smaller bench block this may not prove such a challenge.
