I'd like it if Makita made an 18 V starlock-plus based oscillating multi-tool. I've got a mains Fein one and the tool attachment system is so much better than the ones with the screw up through the middle, so it would feel a shame to switch to that style. However, it seems a waste to invest in Fein or Bosch batteries and chargers when I've got the Makita ones. I don't use it enough that the extra cost for the starlock-plus blades is really an issue and I love the fact I can switch tools or switch the angle of the fitted tool in about 2 seconds.
I replaced the fascia boards and some of the tiles and battens etc on the roof earlier this year. Given that almost every tool I used for the job was cordless, it felt frustrating to have to trail extension cables all round the top of the outside of the house just for the multi-tool.
On a positive note, Makita have started selling starlock-plus blades, so maybe they're working on it?
