I have owned and used both eco and blast boss ( surface tek). Neither pot needs a shaker. The eco pot that I had was very heavy and un balanced as far as moving it around or lifting from a truck. The company was and may be on very shaky ground and took months to ship my pot. Blast boss is a responsible company. They tend to be right there when you need some help. Pots are much easier to move around. I bought all of my stuff separate. It's just a lot of down money to put out to one company if anything goes wrong, but I guess it's quicker to plug and play.
