Which Refillable Pod Vape Is Best?

 　　I have looked at many brands of refillable pod vapes, each claiming to be the best. Is there anyone who can sincerely recommend one?

  　　The only refillable ones I have on hand are the Knife and SMOK ROLO. Personally, I feel they are quite similar. However, the Knife's pods can be disassembled and the cotton replaced if you have some manual skills, while I couldn't manage to open the ROLO despite trying various methods. In this regard, the Knife is a bit more economical.   　　I use the SMOK INFINIX, which is lightweight and portable, and the atomizer can have its cotton replaced manually. The downside is that the condensation of vapor is not easy to expel. Overall, I think it's still quite good; I use it every day.   　　The new releases are actually quite similar, except for a few older models that have some issues.   　　I recommend the Firearm because it is the most affordable and well-made. Alibaba sells it for over 60, and the pods are 7 each, unbeatable prices.
