This is not the OTDR you’re looking for
Bought this is October 2025. Today is March 10th, 2026. I opened the box for the first time two days ago I plugged in the unit and 24 hours later the battery light started blinking. Battery is dead. There is no support to contact for this issue. The troubleshooting steps provided did not help me at all. I would buy a quality product that has support here in the United States if you’re gonna spend this kind of money. Save your money, buy elsewhere Update Reseller reached out to me and offered a full refund. I accepted. I’ll change this from a 1 star to a 3 star and when the refund comes back to me I’ll change it to a 5 star and buy another unit. Everyone deserves a 2nd chance.

buen multitester
Lo he usado un par de meses buen tester debería de tratar de tener videos en YouTube o en su website sobre el uso del mismo seria genial del uso las aplicaciones que viene instalada y buscar la forma de incentivar a la comunidad de técnicos a usar sus productos Debería ser mas notable el stiker para retirarlo para poder cargar la batería
