I looked at those, but decided they were too full of superlatives.. Most people who over brag, don't live up to expectations... Not to mention, years ago, I discovered "PREMIUM QUALITY" is "estate agent" speak for Cheaply made...
I also read their listing, between the lines, and came up with this, which put me off, giving them any of my hard earned cash.
"SOURCED FROM FACTORIES"... plural... so you are reliant on the luck of the draw, depending on which "far eastern" factory was the cheapest this week"
"TESTED TO ISO9001:2000 STANDARD" there is no testing standard defined by the ISO, all that means is they have the ability to create tons and tons of paperwork for management and auditing, and have created their own test criteria, which, with out seeing the paperwork, could just be, "check to see if it is silver, and in the box". Not only that, but the latest is ISO9001:2008, so even their supposed testing, is 14 years out of date....
There were many other things as well, but when I got to the bottom, and discovered that they list one plug fits all... as I posted earlier, the Maverick and Terrano TD both have different recommended glow plugs, and then the TDi's of both of those, share yet a 3rd different one. If Lucas, NGK, and BERU can all be bothered to list 3 types, there must be a reason behind it, however small that is, so their listing can't be right.
With so much choice on Ebay, I always try to stay away from adds like that, and when in the past, I have been suckered in, I have always regretted it... Sometimes, you do get what you pay for.
