My VW started playing up and wouldn't start when hot ( just in case you have this symptom), and also the battery was beginning to grumble on cold mornings. Chose this battery and company as they seemed the best value.
Both were faultless,, best price, battery turned up on time by a nice guy who brought it up to my flat.
Dropped the battery in the next day, spins the 2.0 diesel over effortlessly, no more grumbling from cold and more importantly no struggling to start when hot.
This company and their products is as I say, first class.
