I had a power devil 24 volt combi drill from Argos for 15 yrs,till the charger played up and fried the batteries,it got used 2-3 times a week all the time I had it and well used,like drilling holes through exteria walls with 16-20 mm bits all that sort of stuff,it cost me £28.00p,the replacement is also from Argos and 24v,not quite as powerful as the old one,but still goes through house walls no trouble,this one gets used more,so we`ll see how long it lasts,the run out on both these drills is excellent.I did buy an Aldi 18 volt combi drill once,was a heap of sh-t,batteries never held their charge,everytime I went to use it had to recharge them and after 6 months they died,when the current drill breaks,(its 2 yrs old now),I`ll replace it with another Argos one,oh this one cost me £49.00p.cheers,
Eric.
