Product review (1 stars): Only lasted one month before breaking
I received it on June 28th, it broke on July 29th. The metal insert inside the plastic tube that goes over the shaft just spins freely inside that tube now, making it impossible to engage the timer when you turn the knob. The timer knob this one replaced only lasted 3 months before the plastic tube split, also making it impossible to use. I assume these are designed to break after X-number of days in order to ensure a constant consumer demand. Kudos for that genius marketing strategy, I guess :)
I contacted the seller ... we'll see if the "Lifetime Warranty" is legit or not.

** UPDATE ::: Buyer Beware !! The so-called "lifetime warranty" is a scam. The seller never got back to me.  The "GARP" company doesn't exist ... they tell you right on the package to visit "garparts.co/warranty" for warranty details, but that doesn't site exist !!
