Doesnt look too bad. I personally like having a tri clamp "solvent tank" so i can get in there and clean em out after distilling but im assuming the one theyll send will be clean to start with. The tanks are perfect for overnight/long term storage so youll need one anyway at some point.
Id honestly try going with something a little smaller but more dialed. Theres a ton of people on instagram making systems and getting them tested/rated. Not to say that best value vacs is bad. just kinda limiting in some ways. but for the cheaper price i guess thats what ya get.
And i personally like thinner tubes for closed loops than the 2-3-4" diameter ones. i like a good ole 1.5" but thats just my preference. IMO able to do quicker runs without as much of a "soak"
That could be another downside to the system youre looking at is that its made to do an LB but doesnt have a valve to lock it off from the collection chamber which means you wont be able to get a "soak" of the larger material. But some people just do single washes some do double washes, some just long soaks, etc....
Its tough because only you really know what you need and not working with any CLSs makes it hard for you to pick exactly what you want.
Either way youll have a good system as long as you dont go with super shitty companies like bhogart and the likes.
