Customers are mixed about the ease of use of the rangefinder. Some mention it is accurate and simple to use, very convenient, and easy to manage than a tape measure when making open measurements. However, others say it's a bit fiddly, and not totally intuitive. The instructions are confusing for the calibration, and the manual needs to be readable without a magnifying glass.

This digital laser measuring tape works fantastic. It provides consistent and accurate results. I got my tape measure out and checked it a few times and it was dead on. It's great that it will measure from the back of the unit so you can put it flush against a wall. It also does calculations like square footage of rooms. Fantastic product especially for the price

Best price I have found on a quality and reliable laser distance meter. Small enough to easily fit in pocket, but comes with a case for wearing on a belt.

The box and instructions are in Japanese. I wouldn't have purchased this, had I known that.

It's inexpensive, and it works.

However, it's a bit fiddly, and it's not totally intuitive. I often have to measure multiple times to get it to even register a distance.

I love this product! Great for the price. I'm glad I didn't go with something more expensive. From the measurements I've taken so far it has been extremely precise. The only knock I have,which doesn't effect it's use,is that it came with a couple small blemishes on the face. I wasn't thrilled with that,but not that big of a deal.

Easy to use. Most of the buttons are multi-function, trading off fewer buttons for a smaller size. The manual is clear and concise. Read the manual first, try it for 10 minutes. After that, very easy to use. Even has a calibration mode if you find that you measurement is off a couple of millimeters.
Used it to measure outside distance of about 50' in the early morning hours. Have not tried it in bright sunlight.
