Useful for getting started in watercooling
+ flexibility, although very limited (it does not at all dispense with the need to buy 90° oriented or double/triple rotating mouthpieces). The limitation is that the tube can be bent quite easily or come out of the end cap because the bend is too tight.
+ ease of cutting
- Coiled packaging: therefore is already permanently bent before installation. This results in arcs on connections that should be straight.
- durability: tubes turn yellow in 2 weeks. Considering the price of a loop and the risk of each manipulation (draining, screwing, unscrewing, leak check, filling, air bleeding, etc.), I can't advise them. Although they are no longer transparent, but yellowish, they do not leak and have not come out of the tips.
