Beware if you have to contact customer service, they don’t appear to ever reply. I’ve attempted three contacts and I can’t resolve the issue my product a clamp, multimeter shipped, defective and broken. I have been unable to resolve the issue as now

The delivery process is scary at first because the provider (Fnirsi)gives little information about the shipping state. But I received my unit (IPS3608) 11 days after ordering. The unit seems to work properly. I ran tests on different electronic components, with success. We'll see how well it does over time. I'm satisfied for the moment.

Fnirsi sent demaged device. Geiger-Miller tube was broken. They wanted a description and pictures of that demage. I sent both. Since then CS did not respond to any email request. There is no interest to help their customers. Poor behaviour.

I have purchased three items so far (the DSO-TC3 Oscilloscope, the LPM-10A multifunction network tester and the HRM-10 battery tester). All items arrived direct from the manufacturer (via the Shop app) and arrived within the promised window. The testers all feel well made, work as expected and in my opinion, are exceptionally good value for money. I’ve not had any cause to contact support so can’t comment on that aspect but I would happily purchase from them again.

Ordered directly from FNIRSI website on 31 Dec 2025. Order confirmed, payment taken, but after 9+ days there is no dispatch, no tracking, and no response to email or website chat. Currently unresolved.

Compré 5 cosas, tres comprobadores de componentes un multimetro y un soldador, justo en fin de año, tardo 3 días de más en salir en envío, pero también era mala fecha, mandé un mail al la página y me contestaron al momento al día siguiente teñí el pedido de camino, por la tarde en casa. Pintaba mal pero salió bien. Por mi parte satisfecho y eso q estaba bastante acojonado con las reseñas.

Ordered two items from them in November. Beginning of December got an email with tracking which was handed over to Evri on 8th December. Looks like Evri have lost the parcel but despite attempting to contact this company on four occasions since have received nothing from their support except once an auto response about someone's working pattern changing. Would not recommend anyone to buy from them
