Cheaper on their website - maybe they whack a load on for postage.
i don't ask if the price is right just want to know if the pump is good,thanks
No they are rubbish mate. They're only the most used & well known pumps in this industry & many others, sold across the world, last most users for years without issue under various & demanding conditions for thousands upon thousands of hours.
So, to be honest I wouldn't bother, go & buy something no one's ever heard of instead, you stand a much better chance of a successful & economically returning purchase that way!!
