The "don't buy cheap" argument falls apart if you're an occasional user. If you vape a few times a week, a budget compact might be fine. You won't stress the battery or the build, and the low price is a real advantage. Similarly, if you're just trying CBD for the first time, starting with an inexpensive device makes sense—you can upgrade later if you stick with it.

Also, not all cheap devices are junk. Some brands offer surprisingly good performance at low prices, especially if they focus on a few core features rather than a long spec list. The key is to read real user reviews, not just product descriptions.
