I've ordered from Kramer before and have been happy with what they have supplied. However, unless you are very careful you can end up with expensive products that you don't want and are too expensive, in terms of packaging costs, to return to them. Whilst Customer Services were polite they could not help me resolve some misleading information on their website. I've ended up with two expensive heated water drinkers without the required transformer to power them and without the thermostats to activate them. The additional parts required are not listed on the website which lead one to assume (a dangerous stance to take) that the drinker would work out of the box! The drinkers arrived with no fitting instructions nor product specification. I have to say, at £119 per drinker, they do not represent good value for money. I wasn't given information on how much I would need to spend to make them work I'm VERY unhappy with this and shall not be using Kramer again
