Pros: Stays "hot" for prolonged working sessions...
Cons: Lack of cost effective replacement tips. Look at other WB tool manufacturers.
I've had an L30WB for a couple of years and it works very well for the advanced beginner items I've done, BUT finding replacement tips for the Lenk wood burning products is VERY difficult.
There are a handful of online resources but they all carry only the "universal" replacement tip.
You're pretty much SOL if you want a cone tip, dot tip, etc.
You can order replacement tips directly from Lenk, BUT they want you to pay tax (your local sales tax) AND $10 in shipping!!!
Unless you want a gross of tips for resale, it's not very cost effective to spend over $16 for TWO tips, over $22 for four tips, etc!!!
I strongly suggest considering a different manufacturer...
