I bought the TecSpace 30L, two tank machine in hopes of my wife using it for her food trailer business that never got off the ground. I've had it for almost 2 years and don't use it very frequently since this is now just for home use. I've used it maybe 8 or 9 times for parties or just a weekend of slushies here and there with friends. It works well and does exactly what it is supposed to do but the noise level of the fan is excruciatingly loud. So much that I can hear it from my bedroom clear across the house even with the door closed and when standing next to it you have to raise your voice just to have a conversation. I wish I had a decibel meter to upload the readings. It is mind boggling how loud it is. I can honestly say I would not have purchased it simply for that reason alone. Furthermore, one of the small plastic pieces holding the auger in place broke loose just from normal cleaning with less than a dozen uses. This is a commercial grade machine and I can't imagine how frequently things might break if it were used daily for a business. It does the job but I wouldn't purchase again, especially for home use.
