It is nice to use
It is nice to use but has some poor designs that would make it a much nicer machine for the price. I come from a masonry family and used machines often to mix mortar and sometimes concrete either in bag form or self mix. A grate on top to hold the bag would be nice, the water hook up to be stronger and turn at an angle so it is less likely to get caught and break, a few areas better designed so the dry dust doesn’t get caught in and difficult to clean.
Overall I was able to mix over 40 80lb bags in an hour by myself doing a pad. Slower than a concrete truck but in difficult areas and working alone and at my own pace made it nice. Good work out!
