I still have 2 of the original "performance power" 18v cordless drills...
- they are still in fine fettle having done a lot of work and suffered alot of abuse, the batterys dont hold as much charge as they used to and one of the chargers is kaput. Overall they still are brilliant tools!
More recently I bought an 18v macallister hammer drill/driver. I have treated it really carefully,but have been disapointed with the fact that it has decided to stick permanantly on hammer
I have also purchased a macallister double bevel sliding mitre saw (the biggest one) - so far so good it will easily cut 14 inch and possible with care bigger. It was set up pretty accurately (apart from the laser which i dont bother with). I have not used it too much yet, but have compared it with a similar sized dewalt, the guy who owned the dewalt seemed quite impressed. I suspect it may not be suitable for daily trade use, but then again i needed one this big and compared with hiring charges I now have a free saw which still works.
So over the last 15 years I would say that I have 3 good and one poor experience of these tools
Overall I do not think anyone makes "long lasting" tools anymore, By the way "big-all" is correct I also have a Ryobi oneplus, which I have owned for about 2 or 3 months it is superb and the batteries seem to go for ever between charges and at trade point prices it was actually cheaper than the macallister (the one stuck on hammer) it even came with a free cordless driver, only downside was no box but they are cheap enough
