Was more accurate than I expected. Both my HJC's helmets were listed, and the fit on the chart was extremely close to the real fit of the helmets.

Excellent service--I wouldn't attempt to buy a helmet now without it.

It arrived, easy to use, and the results were easy to read. The helmet I purchased fits great.

Decided to try the Lidpicker system after a "professional" in a big box motorcycle store told me a certain Shoei was a good fit and would break in. I left the next day for a 1500 mile trip and had nothing but headaches. It was almost impossible to remove. I was impressed by Lidpicker's extensive list of helmets that were an ideal match for my head measurements. The HJC helmet I chose from the list fit my crown perfectly. Rode with it 900 miles and loved it. Motorcyclegear.com's price was hundreds of dollars cheaper than the big box cycle store. The only thing I might add is the system does not measure cheek size. My cheeks are fat due to medication. I got skinnier check pads and the fit is perfect now. Will definitely use Lidpicker when I get my next helmet. Highly recommend it.

Helped cut down the amount of helmets to try on significantly. Found my perfect fit.
