I've really been enjoying the clear EMDCC but I've started to develop a crack from the bottom. I was planning on ordering more but this has me concerned. I've been using the carto for about a week (in a rotation with a few other pieces) and I feel like it still has a lot of life left in it if it wasn't for the crack. I noticed the crack early this morning and it was tiny. It's now 3/4 of the way up the reservoir portion and it should start leaking some time tonight at this rate . 
Is this a regular issue with these ? are the solid ones any more sturdy ?
