It's funny you brought that up. I got my MF when it was 1 for $13.00 I was in the process of HIGHLY recommending to them to sell them in 2 packs. Because of my one incident, where I brushed lint deep into the tacky side, I really wished there was a second screen protector. It turns out I didn't need it, all it needed was a good cleaning with soap

They must have had a psychic premonition I was going to make that recommendation.
However, with that said, I do have the 3 pack of Writeshields and the only issue is once you apply one, you really don't need the other two. They are very durable as well. I've had the kit for 2 years or so. Their cleaning kit is a nice addition and I can recommend it.
I know I'm being about as clear as mud here, but to break it all down for you...
I reviewed the Writeshields kit 2 years or so ago. It was at the time the best screen kit out there and it still is a strong player. Some people prefer it because it gives the feeling of writing pen on paper and it shows no smudges or fingerprints. I commented on how I'd find myself not wiping my screen off for weeks and weeks because it repells smudges so well.
Martin Fields is a newer (or newer to me anyway.) They are obviously tough, but crystal clear and feel like writing on the 'naked' screen. Since I've gotten into watching movies on my Pocket PC, the clarity really puts Martin Fields over the top. If they last as long as the writeshields, I will assume they will, then really all you need is 1 screen protector for the lifetime of your Pocket PC.
So value for money, I'd go Martin Fields. If you are a perfectionist, while you are waiting for the delivery (1 week) you could always go with PPCTECHS Kleerscreen kit (

Hope this helps...
