Be careful what you buy from Amazon
The pump broke down in less than 6 months.
Some spring came out of the pump. Since it was more than 30 days, of course Amazon said I need to talk to the seller.
The seller tells me, basically it is 30 days and after that you have to buy parts and repair it yourself. I thought it was odd; usually most things have a 1 year warranty and you would not expect such a response.
I talked to Amazon and they tell me you have to contact the maker. Now, the maker is in Taiwan and I am don't speak Chinese. Isn't this why you pay a margin for the importers? Anyways, the 'purchasing agent' at Amazon tells me, "sorry.... if there is anything I can do"... in typical flawless and meaningless Japanese.
As for the product, its not very good. It looks good and works fine in the beginning but then its not reliable and the as I said, some spring comes off. The importer told me that's how the product is.
