## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product.....read the paper instructions, it explains it
*by D***E on June 12, 2016*

I'm not going to lie. It took me a minute to figure this product out, but if you read the instructions carefully (not on the back of the product, the manual), it makes sense. I use this to do a quick workout and time my set with the rest time. I love it and it gets the job done.

### ⭐ Very cheaply made;  Poor instructions;  Poorly packaged;  NOT RECOMMENDED
*by C***R on January 19, 2015*

This interval timer works, but the instructions are poor and it's not very intuitive to figure out. This timer is made of plastic and is very cheaply made. The knobs were bent, and the abbreviated instructions written on the unit were smeared such that they are barely readable. The If this unit only cost $10, I might give it 2 stars. As it is, it is grossly overpriced for the poor construction quality. This unit came wrapped in a bag, and not in a box.

### ⭐⭐⭐⭐ Good Product | Bad Instructions
*by H***N on March 16, 2010*

I like this timer. It works every time, and it's got a loud (and adjustable) beep that's easy to hear, which makes it perfect for timing my heavy bag workouts. I even like the industrial, retro look-and-feel of the timer. But the user instructions are some of the worst I've ever seen. I followed the quick-reference instructions imprinted on the top of the timer as well as the longer paper instructions. They are simply wrong. I tried them multiple times, carefully following each step. They did not work. So I played around with the timer until I figured out the right sequence of buttons to push. I then wrote my own simple and short instructions -- just three steps to set up a simple workout. So it turns out the timer really is simple to use -- but you'd never know it from the instructions.
