In Detail

A truly multi-purpose 2 in 1 sander with 150mm disc offering a choice of either random with orbital action or orbital action alone. Equally suited to coarse stock removal, fine finishing or polishing.

The slim body/motor housing forms a good grip and, with the auxiliary handle fitted, the operator remains in full control when undertaking coarse work. Similarly for fine work, single-handed control is safe and comfortable due to the machine's excellent balance and palm shaped anti-vibration top grip with finger grip recess. The dust extraction port is to the rear of the pad via an exhaust tube. The tube runs in line with the main body, thus allowing full use to be made of both sides of the machine and secondly forming a very effective hand guard. An aluminium casing houses the gearbox and special seals prevent dust ingress into the transmission.

Supplied with auxiliary handle and storage case.

Excellent in use but not as durable as expected

I have several thousand pounds worth of sanders and use mine for several hundred hours a year, currently I have 2x Festool RO150 Rotex's but have owned or still own 2x Bosch GEX150'S, Mafell UX150, Makita BO6040 (and 2x Makita BO6030's, 2x Metabo SXE 450 Duo's) which just about covers all the main 150mm sanders out there so I can make a very well informed judgement.
For a DIYer or a tradesman who doesn't use this every week for hours, buy it, it does everything the Rotex does for 40% less money, power is similar, top palm rest is more comfy and sanding performance is similar, only downsides compared to the Rotex are difficulty in changing the sanding pad (but they are 60% cheaper if you can get the thing off) slightly worse dust extraction (especially at the edges when holding the sander at an angle) and lack of protector edge guard which is handy.
Both my sanders stopped working last year within 6 weeks of each other, one of them the gears have gone and replacement costs as much as a new sander, I was upset and slightly disappointed but I use my machines heavily, I just expected a little more.
To be fair I have only had the Rotex for a year so I cannot comment on how long the gears last, my feeling is the Rotex has a better engineered gear selector mechanism as you hear an audible click after you change gears, time will tell.
Overall but for heavy use the Bosch is excellent value for money and is a no brainer, for the tradesman and heavy use then the Rotex probably is worth the extra, top tip, don't pay stupid money for Festool abrasives, just buy multi hole discs and carefully drill extra holes in your festool backing pad.
For balance the Makita BO6040 is similarly powered, mine never broke down either, but dust extraction is noticeably worse, the Metabo 450Duo (or Turbo now) is good for the money but lacks power as it is not a true dual action, the Mafel and DeWalt versions are rebadged Metabo units. (Dewalt sanders break easily) The Makita BO6030 is a gentler single action sander and perfect for finer work.
The one overriding problem all the sanders (apart from the Festool) have is the sanding pad retaining nut, if you look after your pads and only change them every year or two then chances are fine dust and resin will work its way into the thread, melt and act as loctite glue and not the temporary kind!!! Heat will effectively weld these two together, I have at least four sanders like this which require drilling to remove the bolt a real PITA. Annoyingly Festool are the only guys who have solved this problem with an inspired fast fix pad which fits by twist and lock, genius. Unfortunately you have to pay Festool a premium for genius but like their Dust extractors with long life bag (no one else does them) and their Kapex mitre saw, they just work.
So buy the Bosch unless you need very heavy and long term use, then take the pain and buy the Festool. Simple. As far as sanding performance goes they are virtually indistinguishable.

Not Bad

Powerfull sander, a bit triky to control but it does a good job sanding on hard wood. Dust extaction is very good, no complains there. The only thing I noticed is that it gets preaty worm fast. I am not shure if this is normal, but I used it for about 2 hours and it was fine. In the agresive mode gets worm really fast.
A protective cover for corners would be nice to have.

not so sure ...

I agree it is a powerful sander , i also agree it jumps all over in rotating mode . Believe it or not it has a PLASTIC (!) gears inside , so when you use all your strength to keep it on the surface it is actually very easy to break the gear inside the head of the sander.
Very expensive to replace !
Still much better than dewalt but not as good as makita BO 6040 .
I am a pro furniture builder and i USE my tools ,a lot,
especially my sanders , i managed to break down the big bosch in three months , had several dewalts
(very noisy !) they last very long but have problems with on/off switches , makita last longer than any other even though i manage to break the dual action switch pretty quick. and 750w motor makes it the most powerful

Great Sander

Very good sander. I have used it for sanding small areas of flooring, doors, etc and depending on the disks used the speed and the finish are great. The backing pad can wear out quickley if you are not carefull tough. But overall a great piece of kit.

Riding a bull.

This sander is very special , it is slower than a variable speed angle grinder or a belt sander and
it has much more vibrations than a normal 5" orbital sander .
On very irregular surfaces you need all your strengt to keep it from jumping all over.(Rotating mode)
But it leaves nice surfaces without the fear of marks and the speed of work is good.
You need the right job for this sander and a lot of energy .But it can save you a lot of time .
