This is a very high quality machine.
It's good of bosch to include the pad options-although for me it seems to function best with the 150 mm pads.
it feels a little more likely to topple with the 125mm pad fitted, especially if you are trying to work one-handed or on narrower surfaces.
The dust extraction is very effective with the on-board collector,and excellent with an extractor fitted,
although again it's better on the 150mm pads.
i bought this machine after i've started to invest in a few festool items, on this ocassion i could not justify double the cost on festool (and also face the choice of 3 or 5mm orbit) -plumbing for the 4mm of the bosch and the choice of 5 or 6 inch sanders in one machine.

i deffinately do not regret buying bosch on this occasion, i've been buying bosch blue for decades now for my work, and very rarely have problems.
This tool says made in switzerland on the label, which along with germany is where i want my bosch blue to come from!
i've got a tile lazer and grinder from china, and a diamond tile cutter from mexico, so come on bosch, don't let things slip!

My only gripe-and it's a personal one, is that i could not order it in a systainer, or a carton so that i could fit it into one myself.
in this regard, for me, l-boxxes arent a patch on systainers.

absolute the top quality rotorbital sander ever used. Fast, strong for remove, really comfortable to use (after 1hour and 30 min of continue using without problem) , if you need a professional sander this is it.

I bought the Bosch GEX 125-150 AVE to replace a very abused Bosh orbital sander (green version) as I was in the process of starting up my own business, I have to say that after 12 months of almost daily punishment, it is still giving as good as the day I bought it. My ONLY complaint is that i need to buy 2 new backing pads, as I have worn out the velcro on both (150mm) pads. But considering I have used 4 or 5 boxes of 50 sanding pads, I can forgive them a little bit. Definitely worth investing that little bit extra, and as usual, Bosch Pro build quality.

I was torn between this and the Makita or DeWalt versions. I always thought this one looked the best and having used (& abused) it on old wooden floorboards I would happily recommend it. The 125 pad is a great addition as it effectively gives you a second sander and the addition of second 150 pad that accepts different brand sanding discs is a real bonus. I will need to replace one of the pads as it really took some punishment with what I asked of it but the motor didn't miss a beat and I feel confident I'll still be using this for many years. I'm only a diy'er but I do believe in buying the best you can afford as it's cheaper in the long run.

I knew my old cheap B&Q own-brand sander had to go when I roughly sanded a single plank and my arms tingled for half an hour afterwards. The next job was to sand 19 jointed hardwood planks in a 6' x 3'6" panel. I couldn't face it, so chose to upgrade to this because of the quoted low vibration. I did the panel today. I took down all the little steps where my jointing was imperfect. I took off all the glue that had oozed from the joints. I fine-sanded afterwards. Beautiful finish, took just an hour, and ruined exactly no sanding disks - each grade looks as good as new for next time. Just the tiniest amount of dust left - hardly detectable. It must be much better than 95% efficient with my Festool vacuum. Cleanup took just minutes. And best of all, no tingling in my arms. I'm blown away by this, and recommend it without reservation. One of the L-BOXX cliips was broken in transit and arrived shattered, but Axminster sorted it straight away, What a great buy!
