I'm guessing that the wired vacuum pens are stronger than the wireless or is it about the same? I got a cheaper model just to test it to see if I liked it enough to buy a better one and I love it! It only just feels a little weak but maybe that's just the nature of the pen I have to touch a few times to get it to hold one....

I've finished a few projects now and am wondering if I even should seal them because I've seen other people say not to. However if I were seal something which is better the liquid pour over kind or the spray sealant? Recommendations and links appreciated!
