I've bought 3 so far, one for my 14g BrewBuilt X1, one for my 14g Spike CF10, and now one for my 7g BrewBuilt X2. It does a great job and gives you an additional TC port and gas/beverage posts.Where it falls short is its floating dip tube kit. It does not come with a short dip tube, but the coil comes with a long one (like, keg length type). I'm fortunate to have a pipe cutter, but I doubt many do. Also, it only gives you the option to add the float ball to the mini filter. I haven't been the biggest fan of these filters and prefer the mini tube you connect to the ball and insert to the tubing.So, coil is 5 stars, floating dip tube kit is 3 stars. Almost perfect.
