This thing is a little pricey for its size, but it's worth it. I recommend having two in your shirt pocket. I've bought one of these for over a year and the second one about 6 months ago. Both still work well and I use them every day. The only downside is that they only work if the connectors are ferrous metal, but that's not the downside of these jumpers.
