    Not impressed for my use

    Posted by Marie Donaldson on Mar 3rd 2020

    Ordered to track my apartment door because I suspect someone coming in while I am gone. Does not count accurately, many false tallies, I was outside my door after zeroing it out and know no one came in and when I came back in it had 17. I sent an email to the address listed a week ago and never got a response, I wanted to return it but it came with no instructions, including no way to return it. Also, beware the battery listed is not the correct battery.

    The Perfect Solution

    Posted by Rod on Jan 17th 2020

    We needed a way to count the revolutions in a skein winder and the manufacturer’s solution was quite expensive. This small magnet counter provided the perfect solution that was cost effective.

    We are utilizing these counters to collect data on traffic control in our operating rooms. They are working wonderfully.

    easy to use

    Love the product. We live in an apartment in a high rise. We travel and are away weeks at a time. When we return we are able to determine whether someone has entered our apartment.

    Simple and effective door swing counter

    Posted by Jason Sabatier on Apr 12th 2017

    This device came quickly when we ordered and was simple to install on our double doors. We used 2 sided tape to mount the counter on one door and the magnet on the other door. Be aware this counter counts door swings also known as buying parties, not the number of people. If you want the actual number of people you would have to spend quite a bit more money and invest in one of the door counters that operates on a beam across the door. For the price this was the best bang for our buck for the information we wanted to record.

    I like the counter

    The magnetic counter is the perfect concept for my weaving loom.

    Exactly what I wanted!

    Posted by Cathryn on Dec 29th 2016

    It's surprisingly difficult to find a simple digital counter that isn't use-specific. I needed something that would count rotations of a large wheel, in either direction. This unit is absolutely ideal and Tally Counter's were fantastic to deal with. I purchased the item online, and it arrived several days earlier than expected.

    Products are great. The service is even better

    Posted by Justin on May 6th 2016

    I purchased these tally counters and when I got them I installed one and realized that there was a defect in the counting. I contacted the company and the gentleman let me know that it was a problem they just discovered and that he would fix it right away. 2 days later the new counters came in (which worked just as they should) and he included a return shipping label. That's great service and standing behind your product. Bravo!

    Solid buy

    Posted by Dan on Feb 23rd 2016

    I actually found this site while researching a backup method to a significantly more expensive sensor+counter combination. Luckily I found this place because my first option did not work as advertised and the only thing the manufacturer had to say was "sorry, we will update our information." This little guy works well and is inexpensive. Cant beat that.
