Query: Filter cracks after a month of use

Bought this product after using an older version of Pur assuming this would also work fine. I was very happy when it attached to my faucet without any additional hardware. However, after one month of use my wife noticed a small crack behind the filtration unit. We continued to use it running water under low pressure while looking for a better model. Now the crack has widened significantly and we have a mini water fountain flowing in to our living room when unsuspected guests try to get a sip of water. Planning to get a pitcher dispenser to avoid this nonsense.
