The one star is not for the tubes itself but for the thomann quality control/package department. I bought this item with a couple of others. They put all of my items in one big package, but the tubes were not secured. One of them actually got out of the package, thankfully the tubes are ok. But please take caution when ordering multiple items, the packaging can be quite careless. When you get the package record a video while you open it, in case anything is broken inside. The product itself is great, i like the sound, the tubes are awesome.
