10 Pieces Magnetic Pentagon Head Screwdriver Bits Set 1/4 Inch Hex Shank Security Tamper Proof Pentagonal Drive Bit Five-sided Figure Screw Driver Drill Bit for Electric Hand Screwdrivers, 50mm

It did not have the size I needed but still a good product for the price.

Worked really well, material is good quality, happy with the purchase

I get it, companies don't want you messing inside of some of the stuff they sell. That could be fine if the devices worked and they din't charge an arm-an-a-leg to fix (plus shipping and handling). So, security screws gotta go. The Saipe 10 piece did the job. I actually tried a bunch of other hacks to get the security screws off, but they were in too well. Glad we found these. Fit perfectly. Certainly seem sturdy and long enough for what they need to be doing.

the set is 2 of everthing rather than 10 different pentagonal secuitiy screws.In my case i got 4 of the same and 1 x 5/16" hex bit

I've not used them yet but I'm giving 5 stars just because they match up with my pentagon head screws (these bits are almost impossible to find). I'll update my review once I find out how well they actually perform.
