Product review (2 stars): Not worth the time/effort/confusion/poor results.
Customer service has been great but we may not be keeping this unit. Firstly, the directions contradict themselves depending on whether you use the detailed instructions or the "quick connect" instructions. Customer service let me know that I could skip a step. Secondly, our CO2 tank is empty after SIX POURED BEERS. The regulator hasn't seemed to work correctly from the start, with the pressure gauge flying up to max whenever the tap line was closed. I'm taking the regulator and CO2 tank in to a draft shop to find out what is wrong before my keg goes flat *fingers crossed* but Smart+ is having a technician call me this afternoon. I will update if something changes but my opinion is that with some help, you could piece together this unit for a lower total price with higher quality components. It took a ton of my time and anxiety to put this together and it's still not working correctly. I'm probably going to have to buy a new CO2 tank and regulator, along with a longer beer line (5'-7') instead of the ~3' line they give you. At that point, all you need is the tower, coupler, tubing, some small attachments, and a mini fridge. I'll practically be half-way to building my own kegerator before I'm done with this $500+ collection of parts.
