La graduación es una etiqueta pegada, si lo manejaran con graduación grabada directo al mismo recipiente te estaría mejor..

Simple but effective. Provides the exact percentage of available ethanol (corrosive alcohol) in gasoline so that preventive and neutralizing measures can be taken to protect gasoline-powered equipment.

Thanks to Amazon I got my money back otherwise it would have been £25 down the drain. Some Einstein at their warehouse decided to put an adhesive product sticker right over the read off label which itself is a VERY poorly adhered sticker onto what is a VERY poor quality plastic bottle. Seriously You are better off just getting a 100ml glass measuring cylinder, the type used in school chemistry labs, and using one of those. I reported this to the seller and whilst they apologised there was no offer of a replacement or refund so once again thanks Amazon.

Makes it easy to test and get an accurate ethanol percentage when mixing different blends. Works well, just wish the cap opening was a little larger to pour into. Still a solid and reliable tester.
