Cierta - Insulin Cartridge Filling Tool for Tandem t:Slim X2

For someone who has poor eyesight this was a big relief and stress savior.

This is the 3rd one of these fillers have purchased and the only one that works as it should. Centers the needle, has a depth stop, and even with my arthritis I can easily fill the cartridge.

I attempted to purchase this to help fill my insulin pump tubing. It was never filled, for whatever reason.

It doesn’t match up very well. With less effort it can be done free handed . The big issue is to get the syringe and the reservoir matched up so as to fill it.

Just switched to a new pump and the site change system is different. I bought this to make things easier. Nice though not necessary BUT I love using it with every site change as it enhances the cartridge change procedure for me. Easy. I compared it at less expensive ones and chose this one. I like it. It’s a preference.

This provides very accurate alignment for the syringe to go into the cartridge. Had purchased a cheaper one and it was not anywhere as good or accurate!

I had cataract surgery last year. It changed my close up vision, as it does for many. They waited soooo long to give me new lenses. Filling my cartridge was very difficult. Buy this as something essential to keep in case: a punch to the eye or a softball, a broken arm, tendinitis. I wish I had seen this before I needed it! A great problem solver that works!

Love the idea because filling T Slim cartridges is a nightmare for my bad hands. Unfortunately it is hit or miss. The cartridge doesn’t always line up right in it so the needle doesn’t always go in right.
