Review on Magnetic Tool Holder - Lisle 21400: Improving Organization and Efficiency! by Mirzet Gosselin

I have both the 1/4" and 3/8" versions. - I bought the 1/2 inch version but had to send it back. Works well, the 3/8 version takes a punch or chrome from 7mm to 21, but let's face it who has anything over 19mm or under 9mm in 3/8. The 1/4" version also has more slots than you actually need - waste of space. The 3/8" and 1/4" versions hold sockets well and work well in shallow drawers. Unfortunately, the 1/2" fits -Version not on 10mm to 24mm.(Standard sizes for 1/2" sets). The 1/2" set doesn't have a magnet to hold it in the drawer - instead it has legs. The legs tend to slide even with a good drawer liner. Even if a 3/8" is theoretically set to 1/ 2 jacks would fit, the channels are not large enough for at least 1/2 drum jacks. You should make 1/4" and 3/8" 24 slots to save space in the drawer. You need to make a 30 slot half inch version.
