Just what I needed. I like to keep extras on hand. I plan on getting some as stocking stuffers for friends.

I'm always walking into customer's homes and leaving something behind.  If I have a small job, I'll throw this on, so I don't set my tool down and forget it.  Just right for small stuff.

Handy addition to my bag of tricks, when on service calls.

this is my spare cartridge, when I use my last one on hand I always order another so that I never run out of ink.

Good to keep on hand when the other one goes, or install if you don't have one.  Add it to an order.

I like having these on hand for guests and to be able to replace them regularly. I'm the kind of person who won't remember to pick them up so I have them on auto-ship. I've had SoniCare but I think I prefer these. I like the idea of a brand new toothbrush every month.

I mostly have this set for a back up in case the other set I have breaks and I'm glad I have them.

I believe this will be fine, they appear of good quality, I have as spares so I will have them when I need them

If you tinker with a lot of stuff as I do you will find these handy for those tamper proof bits .Don't use them that often but when I do need them its nice to have verity.

I always keep the little Swiss knife on my keychain and after a while I will lose the pick that came with it - my fault always, they never fall out on their own. So having a supply of these on hand is necessary. They're great.

I like that I can have these on hand in case other ones go bad, which happens about once a year.  Thanks

I take this as part of my knitting-on-the-go materials.  Conveniently packed so that I have whatever I might need to help with a dropped stitch or any other task.

I have more than one of this item and find them to be useful and do the job I needed done.
