Well I've been buying Ryobi one + cordless tools for last couple years.
Yeah was unsure when I first got one, very sceptical.
Reason was I wanted an impact driver, their impact driver, whilst a little heavier than others, is half as powerful again!
With a 18v 4Ah battery is unstoppable! Drives anything!
Then bought a combi drill on offer with 2 4Ah batteries giving me a combi an impact and 3 4Ah batteries all for less than £300
And I've just bought the multi tool for about £70 naked!
It's very well balanced with a battery, good work light and one snazzy feature, the head detaches and can be turned through 90 or 180 degrees so the battery and body can be turned away from the cutter allowing access to more awkward areas.
They have a 5Ah battery out this yr too, may already be out, dunno tbh!
All three units are very reliable and the batteries have a kick like a mule!
I'm pleased with them and they don't break the bank!
