I liked the large gauges and the look of the tank mount. Both ideas are very attractive. both failed after only a few months. They are completely closed. So there was no way I could open them up and see if I could fix/restart them somehow. And it was VERY difficult to peel off their adhesive backing from the glass side of the tanks. Too bad really. I liked the concept. Back to old fashioned glass tube readers and suction cup thermometers. $3.99 each.
