Hi - I have one of these Labotims and I don't think it's the world's greatest timer. It's a good piece of digital kit but it falls a bit short, in my opinion, in that it has only a 2-digit display. This means it displays times like '9.8' seconds up to 10 seconds, but once it reaches 10 seconds it displays only whole seconds, and it does this all the way up to 99 seconds, which is its maximum time. In this respect it's a bit amatuerish, which is a shame, because otherwise it's a nicely made thing. If it had a 3 digit display, everything would be much better. I keep mine as a spare in case my Wallner MP-104 enlarging meter/timer breaks down. The Wallner is a much better item, but more expensive. I print with a Focomat IIc and a Varioscop 6x9. I also have a great enlarging app for your Palm organiser, if you use one. Cheers - Andrew
