I bought 4 (8L) kegs, and 4 of the "heads".. I have poured through 2 at this point.Initial thoughts were:Really "plastic" smell when opening. Did not seem to affect the beer. This seemed to dissipate after the first use. Really fiddly heads that took a while to get them straight to not leak. Please check for leaks before leaving them alone.. Maybe gaskets would help? I don't like trying to over-tighten plastic.I used them. I like:The format/size. These fit great in small places, an be used sideways(with a check valve). I can fit 3 inside the pancho keg cooler with a sodastream CO2 tank, so some selection to bring with is nice. The price(maybe), at least I'm not out a ton if I leave them somewhere etc.. I dislike:I don't always get as good a connection with the ball-lock connectors which seemed to result in "hammering" until I adjusted the connector or held it tight through the pour.when cleaning them, do not try to empty if full by just turning them upside down, they collapse, and seems like that might be bad long-term. Live and learn I suppose (See picture)The "feet" seem really dinged up. I don't feel I abused them. I do have concrete floors in my basement, but it goes beyond scratches into "dents" which again, seem like will be a wearing point over time. and it almost looks like where it dented there may be some separation between layers?I don't feel comfortable cleaning as hot as stainless, fortunately Liquid PBW exists now.I'm neutral on:Not being able to get my hands inside to clean. This is somewhat offset by the ability to see the insides. I run a lot of standard sixtel kegs, so not too big a deal, as my normal keg-washer should work. Over all, I think they are going to cost more than used stainless kegs, less than brand new ones. This depends on how long they last I suppose. Again, the format seems nice, and they are pretty portable, and with the flexible dip tube, can be loaded on their sides..As an aside, I bought the "starter" kits. The individual bottle price seems to have gone down, while the tapping heads went up a little. This may make them a better long-term price if the kegs cost less.As a second aside, after my initial review, MoreBeer reached out, Top notch customer support. I will continue to buy from them as the first stop(after my LHBS of course).
