It's got that middle of the road build quality. Not garbage but not real solid like its made of thick strong metal. But a lot of stuff is made that way. It comes with a nice drip tip everything operates smoothly so what sucks? I am not a big fan of bottom airflow on drippers. You over drip and you have juice coming out of the bottom. It does not give you better flavor so stop doing it. I listened to all the youtube reviewers saying this is great. So I bought it. They all lie and just market products. This has nice smooth airflow but the whole thing is muted in flavor. Yeah you can close off top air flow for a little more flavor but its not that much. I tried it all different ways. It chucks the clouds but if you are looking for great flavor its not there. But because of the affordable price I don't regret buying it. They gotta stop using phillips head or flat head screws on drippers. Hex screws are the best. Those of you that say it strips its bc you are using the cheap crappy tool that they give you. Go buy a quality hex head and you will not have that problem. Don't listen to these reviewers telling you phillips head are the best. They are not. You go to tighten and the head will pop out. You can't get as tight as a hex head. I am sick to death of all these youtube reviewers lying to sell a product for whoever that sent them free sh*t.
Im in love with this drip tip, pretty good looking. The rest of the RDA is not as good. The post screws suck pretty bad, really, they are a little less than decent, im guessing they will strip after a month or so, good thing it comes with some spares. The airflow its really amazing if you are using both types at the same time otherwise you will hear it whistle specially with the bottom airflow holes shut. Im not really happy with its performance but overall it LOOKS nice
