Probably the best one for the price
I was replacing a previous unit which now receives on a modest review score. So I read reviews of several models before buying this one. Of course, it it not possible to confirm that it is working properly unless you intentionally mis-wire an outlet to see what it shows. I did not do this, which explains the 4-star rating I gave it for Accuracy; it may well deserve 5 stars. However I can report that the display is easily visible and shows that the power outlets I tested were all good (no faults). It seems well made and should not crack apart unless stressed greatly. I did not do this either!

Muy buen producto, me ha ayudado mucho a instalaciones eléctricas para hacer comprobaciones rápidas. Lo recomiendo mucho sin problemas, posiblemente lo único malo es que las instrucciones no están en español solo ingles, no tengo problemas para leerlo pero seria bueno tenerlo en español de igual manera.
