Kundeanmeldelser for VEVOR 10L ultralydrenser dobbelfrekvens ultralydrensemaskin med varmeapparat smykkerenser for deler smykker briller ring protese plate kretskort 28/40KHz

Spedizione veloce ,arrivato in pochi giorni. Per mia sfortuna è arrivato danneggiato dal trasporto . Un paio di ammaccature sulla carcassa esterna . Contattato il servizio clienti mi hanno proposto un rimborso parziale per l accaduto .Visto che dopo una breve prova l' apparecchio funzionava normalmente ,ho accettato il rimborso . Successivamente l'ho messo in funzione per pulire delle manopole di un mixer ,e il risultato mi è sembrato buono . Farò dei test su altri oggetti . Niente da dire in quanto servizio assistenza ,mi hanno contattato in breve tempo . Ho consigliato di imballare meglio i loro prodotti ,o cambiare corriere , perché non è la prima volta che mi arriva un pacco danneggiato esternamente ,guarda caso dallo stesso corriere.

Reinigungsleistung des Gerätes ist in Ordnung. Heizung ist von der Leistung grenzwertig gering. Temperaturerhöhung ca 10 Grad pro Stunde. Wenn man warmes Wasser einfüllt, ist es erträglich. Hier würde ich zur verbesserten Version raten. Hatte aber wegen der zwei Frequenzen zu dieser Ausführung gegriffen. Hier ist die Artikelbeschreibung fehlerhaft. Das Gerät verfügt lediglich über eine Reinigungsfrequenz von 40 kHz. 28 kHz ist nicht auswählbar. Es kann zwar nur eine Halbwelle ausgewählt werden, das halbiert aber nur die Leistung, nicht die Frequenz. Wer das überprüfen möchte, kann sich gerne die Anleitung herunterladen. Klare Falschangabe in der Produktbeschreibung! Kundenservice ignoriert das Problem, schickt einfach ein PDF der Anleitung und schließt den Fall. Dreist!

This is NOT a 28khz machine. It is only capable of 40khz operation. Customer service will try to tell you the semi wave function changes the frequency, it does not. This issue was not resolved! You are still falsely advertising this product as 28khz when it does not have that ability.

I paid a machine 350€, now they sell out for 200€. Machine was working 1 month, they send me a new circuit board, I changed by my self a board. I realised that the old circuit board fitted to the machine had been in use for at least five years and had already been repaired. I fitted the new circuit board; it had been working fine until now, but the machine has stopped working again. I use the machine once a month. Don’t buy it !

Filled mine with water for the first time and it leaked. I file a claim on this unit to get it swapped with a working unit. Waiting for vevor to swap it out.

Le produit reçu ne fait que du 40kHz, pas du 28kHz. Pas de réponse sur mes demandes de retour

does not honor warranty. unit is defective while still in 1 year warranty. company send " replacement parts " for us to fix ourselves. parts are wrong and do not work. company offered $30 to keep completely defective unit and will not replace with a working unit. Will be filing a consumer complaint. they will not honor warranty, refund, or replace unit.
