I have a set of these, I think they're really good. Only thing I don't like is when your second fixing t&e, i use the method of using the earth to tear the sheath back (probably get hassle from the older guys about this method hahaha), which with snips is easy, small snip end on to the t&e and pull the earth out. These pliers won't allow you to do it really, you can mess around and try to use the shears part to do it but it's not the same. Great go to tool for anything else though.
Amd definatly get the sprung ones! Using the stripping notches with the sprung feature is brilliant, fast, and no fear of damage to the conductors. Same when trying to get conductors into an accessory, the end of the pliers allows you to grip the conductor with out risk of damage to the insulation, recently used that feature to get 6mm2 into an awkward oven termination.
Apart from my t&e second fix gripe, I would recommend these! Especially since they're coming down I price now too, were around ÂŁ50 when I first saw them around a year ago.
