These are the special K-Pads that are supplied with all Xecuter RROD Pro Repair Kits.
The Red Ring of Death (RROD) syndrome can be a common problem and renders your console unusable. The Team Xecuter RROD K-Pad fix consists of specially formulated heat pads that fit over the memory modules that commonly break and lose their connection, thereby renewing the connection. This bulk pack contains 40 K-Pads, enough pads to repair 10 Xbox 360 consoles. It is designed for customers who need to repair a lot of machines and have all the tools available.
They are designed using a special extra tough material that has an extremely high heat tolerance (K-Value) and are used to replace the 4 stock memory pads on an Xbox 360 and help stop most RROD issues.
There are 40 pcs in each pack (4 used on each Xbox 360 - so enough for 10 Xbox's)
