hi @tylerank611 please please don’t worry too much about the tubing. it has never been an issue for me for 12 years. it allows you to use site locations such as the belly or top of the butt and you wont have a huge bump to worry about. i stick the pump in my pocket about 90% of the time, clip it to my pants the rest of the time.
all the pumps in this configuration have a permanent pump with a display and buttons, and you only switch the little infusion set and reservoir every 2-3 days. t-slim requires a recharge because it has a permanent battery, other pumps have a replaceable battery.
these pumps have options for infusion sets such as straight or angled, teflon or steel. I don’t have a t-slim but I read their specs and it seems reasonable. good luck!
