Ventilateur extrêmement bruyant ! Plus bruyant que la pompe qu'il contrôle.

une touche du panneau de commande reste coincée !

Buenos días, no pensaba escribir pero ya que me enviais esta carta lo comento estuve a punto de devolverlo porque vino con el potenciómetro partido y parecía que ya había sido usado porque venía con los parámetros tocados pero como me urgía ya lo usé y de momento parece que va bien Saludos

Hallo, mein Name ist Herbert Hoffmann, ich hatte bisher schon 3 Frequenzumrichter von einer anderen Marke gekauft ( habe noch einige Maschinen, die umgerüstet werden müssen, kein Drehstrom ). Ich habe das Gerät bei Ihnen gekauft, um noch andere Frequenzumrichter zu testen. Ich konnte das Gerät noch nicht testen, da keine deutsche Bedienungsanleitung bei der Lieferung dabei war. Bitte senden Sie mir eine deutsche Bedienungsanleitung, damit ich das Gerät anschließen kann. Danke und Gruß Herbert Hoffmann

This is a really hard review. The product was good however the customer service sucked. About the best thing I can say is Vevor should not advertise "get it by" date unless they can deliver on that date. I had an issue that I needed the inverter basically overnight for a mechanical issue that needed immediate resolution. I ordered the device on Saturday the 31st of January, expecting a delivery date of 2/2 which is what was advertised. Mind you, I did not have any options on shipping, because of this I expect the vendor to select a shipping method that would get the product to me on time. I received the product 5 days later than the advertised date causing me to have to secure a another controller and install it. This cost me so much time that paying a couple of buck for shipping would have been a better way to go. Heck this box weighed about 3lbs and is very small, In fact I could ship this box with 2 day delivery for about $13 bucks and that is at retail. I am sure that Vevor could have done two day shipping for $3 or $4 bucks which I would have paid for if I had the option. I did get the new inverter installed on Sunday and it appears to work as advertised. My biggest issue is customer service making excuses for the slow shipment, telling me that they shipped it on time. This is not an acceptable excuse as Vevor gave no option on shipping. This box went all over the western US going from Chicago, to Colorado to Los Angeles to San Francisco then to Sacramento. While I am all for site seeing, not for a package that was advertised "get it by Feb 2"

Not work properly
