I use the VEO, along with the Contour Link meter, this is the only meter that wirelessly links to the Medtronic pumps but is absolutely brilliant, I use it in combination with my other meter (A Glucomen LX plus for the ketone use) and always before a meal so that the Bolus wizard on the pump can give me the right amount of insulin for my meal.
Regards the stickiness of the canulas, I started with the Mio sets, but found that I was sweating too much and they would come out very easily (and way too soon) but was also supplied with 2 Quick sets which I tried during my Holiday in August, these proved to be much stickier for me so I inquired about getting them, and was told that all I had to do was ask Medtronic for them. I have had them for just over a month now and not had any come out due to sweating, they stay in until I need to change the sets. I do not use any extra tape.
