The Wobl watch is one of the original “potty watches”. Its main purpose is to provide vibrating and audible reminders as well as tell time. The original watch has a pretty durable cloth band that is comfortable and easy for kids to use. The newest version, Wobl + is water resistant. However, with the newest watch the band is a bit floppy and seems that it could easily rip over time. Both versions are easy to program 8 timers daily. Several families where the watch malfunctioned or the band broke, were able to get a replacement from the company. Overall, the Wobl and Wobl + is an inexpensive watch that is a better bet for younger kids that need reminders.
