I ordered this because I couldn't find the adapter I used, it was the one you squeezed the sides and put on the faucet. This screws onto the included faucet adapters (assuming it fits one of your needs). I found the device generally squeaky, cheap and too light. After I installed it on the faucet and put in the included filter, it started both squirting out of the carving area and spewing a few black chunks into my water. Assuming it was charcoal residue, I let it run for a while, but after a few gallons it continued to do so. I then removed the filter and tried one of my old unused blue filters and it came out clean straight away. As for the threads, I wrapped the threads in tubing tape and tightened as far as I felt comfortable given the cheap plastic that still lets water through. I don't know what they did with those in between model styles things, but these new ones are absolute rubbish. They also include a non-removable battery. Hopefully you will get a brand new battery as there is no battery pull label to activate it when installed meaning it is active from the day you install it.
