well...i suppose each of us are individual. I had a Medtronic pump. I had issues as to where I could wear it. Wearing the actual pump on me was a problem. Alot of the time, it was and had to be visible. Either clipped on my belt and then having tubing go under my shirt. sometimes the tubing crept out. Sometimes it kinked. I tried to wear it on my leg a few times but due to the design of the canulas, it pulled when i walked. It hurt alot. I also bought the holder to wear on my leg but it wasnt comfortable for me. i found the pump bulky.
The Omnipod patch is a quarter of the size. Its 2.5cm square and about half a cm thick. Its light, you dont even feel the weight of it and no tubing so I wear it on my triceps, thighs, calves, abdomen, pecs, back - upper and lower. I dont share my bed with the pump or all the tubing anymore. I used to role into the tubing at night and sometimes got tangled. Sometimes it pulled right out. Sometimes Id get out of bed and id hold the pump to go to the loo or something and the tubing caught on the door handle and ripped right out. For me personally, it was a disaster. I had mine for 4 years. I only realised the freedom of the Omnipod after I used it for the first time.
