Most sub-£40 dry herb vaporizers are junk. They use cheap heating elements, ship with no replacement parts, charge over micro-USB, and fall apart inside a year. The market under £50 is mostly badge-engineered devices from the same handful of factories, sold under a dozen different brand names with thin warranties.
Professor Herb sits a bit further up. Their Herb Pro uses a 316L stainless steel chamber — the same medical-grade alloy you'll find in devices three times the price. It charges over USB-C, ships with a replacement chamber screen and a proper cleaning kit, and runs a 900mAh battery instead of the 500-650mAh you typically see at this price.
It's not a flagship. It won't out-vape a Mighty+. But for someone trying dry herb vaping for the first time, or anyone wanting a backup unit that costs less than a takeaway, it's the most honest device at the price point.
