Although I like the pump, I had a really bad experience with this company. They claim delivery takes 48hrs and this is why I did my purchase since I needed the spare parts and I was in a specific place for a limited amount of time, so I placed my order. The order arrived 5 days later when I wasnt there anymore. I contacted customer service several times to change the delivery address (when it was still possible to update) and they didn't do it. When I asked for a refund given that I had been misled by the website information, specifically repeated at the point of payment, they said I needed to send the parts back, knowing already my case.
They also said the 48 hrs means from the moment they ship their products to the courier, not the customer, again this is very very misleading, as a customer you read 48hr delivery and you expect this to be to your door.
I think they claim to be customer centric but I found the support to be very poor and the information on the website to effectively be a lie.
