CamybbMulti-function Professional Handheld Electronic Digital LCD Chronograph Timer Stopwatch Sportwatch

Very useful for my therapy sessions.

I'm an on-course official which at times require me to time more than one player at the same time. Having multiple stopwatches allows for me to achieve this.

The speaker can easily be disabled by placing a piece of tape over it to interrupt the contacts. It is on the inside back cover. The battery can only be replaced by removing the back, a bit annoying, but it is a standard LR44 button. BE WARNED, the buttons make a loud click sound when pressed, which can’t be prevented, so something to be aware of if your video village tends to be right on set.Fairly new so can’t comment on longevity, but in my experience, even expensive stopwatches give out eventually, so are never worth the investment.

When riding the ole exercise bike, how long did I ride?

Product information is missing relevant information. Stopwatch does not have a "Off" button. It remains on until the battery is depleted. I do not know how long that takes. If battery lasts a year or whatever, the product info should state as much. Replacing the battery requires a jeweler's screwdriver to remove the back panel. There is no mention of this defect or what battery is required. I realize this product is inexpensive, but why Amazon lists it as an "Amazons Choice" selection is somewhat suspect.

For various purposes. Easy to use

It is durable and light. Functions are easy to navigate through and it serves its purpose.
