### 1/5 — Un robo

*2020-12-10, version 2.3.7*

Es un robo no sirve de nada quisiera saber cómo recuperar mi dinero

### 1/5 — Don't buy it !!! It doesn't work right

*2017-07-22, version 2.3.5*

It doesn't work right 😤 I just wasted my money and time...

### 1/5 — Don't waste your money

*2017-02-17, version 2.3.5*

You have to calibrate every single time and when you are measuring it just runs off even when you move an inch.

### 1/5 — Do not buy

*2016-08-27, version 2.3.4*

Rip off. After watching video multiple times still couldn't figure out how to use it. Center after it. Should be more user-friendly. Try something else.

### 1/5 — Don't waste your money

*2016-01-02, version 2.3.1*

Just bought it because I need to measure something hanging on my wall and the measurements it would give me were way off. Also it doesn't convert to inches and if it does then it's hidden in the app or the switchover just doesn't work. Don't waste your money on it. You'd be better off just buying a real measuring tape.

### 1/5 — Terrible waste of money!

*2015-07-18, version 2.2*

I watched the tutorial, followed the directions, and then measured a few items. Not even close to accurate!

### 1/5 — No good

*2013-11-03, version 1.4*

This app does not work. Save you money! Tried 15 times exactly the way they show and it always measures out of control! Move it 2 inches and it reads like 200 inches. Again save your money! Wish I could get a refund!

### 1/5 — Not even close

*2013-11-01, version 1.4*

After 15 min of practicing the measurements are anywhere from 20% to 300% of the actual distance.

### 1/5 — does not work as advertised. I want my $1.99 back....

*2013-10-27, version 1.4*

doesn't work

### 1/5 — I thought this had a calculation for inches??  I am not British!!

*2013-07-05, version 1.3*

I need a calculation for inches!!
