Question: how does the memory feature work.  Need a timer for 2 min that does not have to be reset everytime it is stopped
Document: This CDN has a (1) "Count Up" feature (useless to me), (2) a memory (also useless), (3) tells the time, and (4) times ONLY ONE item at a time. The CDN also has a brain drilling tone whenever a button is pushed...and if you try to avoid the tone by pushing the timing button for rapid number changing, it ZIPS past your target time, and you end up having to reset it repeatedly!
I keep the memory set at 20 minutes--the time it takes to freeze homemade ice cream--but  the memory can be easily erased and reset to something different whenever you like. You do NOT have to set the timer and allow it to run to completion to invoke the memory function (a requirement with many other kitchen timers). Instead, the memory is set independently, by using the regular Hr.-Min.-Sec. buttons and then hitting the Memory button.
There is one &#34;memory&#34; that you can set. For example, if you often need a setting of 1 1/2 hours, you can save that to the memory.
I was looking for an easy to use timer that could be set to count down from 2 or 3  hours, and be easily reset for repeating this time frame, and not too difficult to do at night...  (to remind to get up every 2 hours...)  This one does the job! And it is adequately loud. Too many timers will only count down only from 99 minutes. We also like the ability to switch it to clock mode and use for an alarm.
This timer is easy to use and has  a fairly loud  ring. The display isn't very big, but is fine for people with average vision.I like the count up and count down feature and use both functions daily.It's a pretty good timer. It's small, only 2" x 3". I would prefer a larger timer with a bigger display.
I have only used this a couple times and it's already broken. The 'memory' feature was why I bought it because I didn't want to have to press the minute button 20 times each time I wanted to use the timer (dozens of times a day)....the 'memory' feature is now broken, button doesn't seem to work. I have only had this for a couple weeks. Do not buy this.
Digital timer and clock memory feature is just it shows. Very easy to use and use it every day while working out.Also, shipping was much faster than stated on website.Thanks!
To be even more honest - I'm very proud of myself for not smashing the thing on the floor!2. The worthless memory button should actually be used to switch back and forth between the clock and timer. At least this way you wouldn't screw up the clock all the time.I HATE this timer.D.
Many years ago I worked as a Barista at Starbucks. We had a method of setting a timer for 10 minutes and doing a "sweep"- one of us would shift from behind the bar to the sitting area, do a quick pick up of used dishes, wipe off tables and chairs, refill milk and sugar packets, etc. We used these timers exclusively. We'd set the memory button to 10 minutes, and every time it would beep, we'd reset it to start over and do the sweep.
The only negative thing I have to say about it, is that it is quite small. At 2" high by 2-5/8" wide, it is slightly smaller than a credit card. Because my household has two cooks, I use this timer alongside another excellent timer, theRobic Three Memory Timer, which is limited to 99 minutes but which remembers three frequently used time settings.
Answer: set the time you want and then push the memory button. I use mine to remind me to take my medicine. I need to get another because this did not last but 9 months.
