The first point to raise it make sure you have a compressor suitable for running this soda blaster. Otherwise the compressor will be running continually to maintain operation and / or you will have to keep stopping to let it catch up. It's not a fault with the gun if you do not have a suitable compressor.
Moving on the unit seems good quality and robust. For a DIY person like myself, I can see it lasting many many years.
The bowl / container is a reasonable size compared to many cheaper blasting guns that are out there.
A water filter is recommended to run along with this.
Partner this with another gun for media blasting and you will have a great set up.
