My Oliso had problems after a year or so, when I called the company they immediately replaced it at no cost, I experienced great customer service. The replacement is doing well, after over a year (not sure of time, it get away from me).
It does have a switch so you can stand it on end if you don't want to rely on the pop up. Friends were sewing with me & kept forgetting not to stand it up, next time I'll use that switch.
