Nice case
Purchased this for my tslim since the one that came with it was showing it's age.  Overall the case has a nice "feel" to it.  I like a case that can easily fit in my pocket.  I do not wear my pump on my belt so something that wasn't too bulky is what I was looking for.  The case is a soft silicone material and protects the pump screen with a bit of a lip which is nice.  It also protects the cartridge as well.  Now when the time comes to change the cartridge it will require that remove the case so I am not sure how, over time, this will affect the fit after a few months of changes.  I will come back and update my post "IF" I notice it stretches out too quickly.  Overall for the price the design and quality feels good.  It is thick enough to offer protection without the bulk.
