Our six year old son is currently MDI with syringes, Dexcom, and CGM in the Cloud. We'd like to start pumping before 1st grade. We're considering primarily the Ping and OmniPod but open to the T:Slim. Minimizing site change pain and overall pump system reliability, durability and accuracy are the most important factors to us. Other pump-specific quirks can be dealt with. I like the Ping because it has a pump remote, seems reliable and durable even if not "cool", is compatible with our existing OneTouch strip Rx, and might offer an integrated Dexcom upgrade. We really like the cordless idea of the OmniPod, but I'm not sold due to many of the issues I've read about here and elsewhere. I'm interested in T:Slim because I love tech that pushes the status quo. Tandem seems to be doing that, though I'm not convinced the T:Slim is ideal for a rough and tumble six year old boy. I would appreciate any advice from people who have used these pumps on younger kids. How is the site insertion for each of these pumps? I'd really like to hear from people who have used more than one... why did you switch, and are you satisfied with the switch? Here's my +/- list for each pump. Ping Positive Waterproof Long battery life Ping Remote/BG Meter (Compatible with existing OneTouch supplies) IOB for food and correction Potential future Dexcom integration / upgrade Negative Corded Loses IOB during battery change OmniPod Positive Cordless Waterproof Long battery life Automatic Insertion Many claim insertion is relatively painless Negative Reliability problems, i.e.: Pods falling off when wet, post-site change highs (old style pods only??) Some complain about site insertion pain IOB for correction only?? Freestyle meter / strip issues T:Slim Positive Modern UI, easy to use Tandem is at the forefront of pump tech (bionic pancreas, etc) Negative Rechargeable battery Not waterproof Cartridge recalls / issues? No negative correction?
