There was a problem with these tops as water cooling UK recalled all theres i belive because of a weakness in the material. I may be wrong though.?!
EDIT
EDIT
OCLabs DDC tops have been recalled for the second batch (Don't worry we have only sold 2 from this batch and they have been replaced, so no need to panic!) There was an issue with the chemicals used to make the plastic when vacum formed making them very week..
At the moment we really do have no ETA on the replacements
