The Tikkina is clearly the best value in small headlamps we have seen, and offers performance that will meet or exceed most people's needs. For around $20 you get a a very capable headlamp with an impressive spot beam and incredibly long close-proximity mode battery life. It is super easy to use, with a single button and only three modes to click through (Low, Medium, and High). While many headlamps fell short of battery life claims, this one outperformed what Petzl said it could do for close proximity use (high mode is another story, see below). This headlamp outscored every other headlamp $20 or less, and offered performance that rivals lights costing 50% more. Yes, there are cheaper headlamps out there, like the Energizer Vision HD, but with these less expensive models could not match the Tikkina in quality.
Petzl offers a nifty USB rechargeable battery for the Tikkina, that is worth mentioning. At $30, the Petzl Core Battery provides more power than regular alkaline batteries, yet with the convenience of USB recharging. If you use your headlamp regularly, or if you travel to areas where buying replacement batteries is an issue, consider the Core as a slick solution to get a USB rechargeable light at a good price.
