I have 2 Timer timer devices, one big and one small. Both have problems with the battery section. I had to break the battery cover of the small Time timer to open it because the small screw was too tightly placed and there wasn't any tool in my house hold that would open it. So had to break it to insert the battery. Big Time timer had so tight compartment for batteries that we had several people trying to insert the batteries. Somehow we finally managed to get them in the compartment, but I am pretty sure we won't get them out anymore when they need replacement.
Otherwise the product is good and userfriendly. Works as specified. Only problem is that the big one shows that the time has run out already but it takes about one minute more for it to play the alarm.
