Short & sweet review Mark, & as always, awesome pics!! {:-)
At this quality & value for money at this price point for the prosumer market, it looks like the Exobar Office Pulser has really stepped up to the plate & delivered a home run on this one! They really should have had a pressure gauge on this..., it would make it so much easier to dial in your particular brew/steam temperature. For easy viewing of the water level through that sight window, they should have had a clear strip added there on the opaque white water tank!
Excellent work,
Cheers!

Probably not for a while.  I know Mark's been very busy & his mother just passed away on Monday.

Hi Folks, Hope I'm not stepping on toes here, but I just bought my Expobar Pulser and I have noticed a number of design changes since the "first look" was posted. I was somewhat surprised, since I had based some of my initial pre-purchase impressions from the info on this website. I am pleased with the machine, but I also think it's worth mentioning some of the changes that I have noticed.

The water reservoir is different than the one pictured. It holds 96oz by my measure, and there is a single hole in the center of the top. I assume this is an improvement over the earlier design, but I can't speak from experience. The cup warmer design is different. There is a split panel, with the rear panel, taking up about three quarters of the top, recessed about 1/4" more than the front quarter. There is no diode on the front panel to warn when a safety has been engaged. I'm not sure what the machine does now to tell the operator that the sensors have detected a problem.

The low profile feet are a welcome feature. The unit now sits about 3/8" above the countertop. There is no longer a water level viewing window. But there is a weight activated switch that prevents the pump (and I assume, the heater) from operating when the water needs to be refilled. The power switch is lighted, and there is a second light just below and to the right. This light indicates that the heater is engaged.  

That's all I know about at this point. Granted, these are small design changes, but they might matter to someone who is basing their opinion from the review posted here.

Overall, I have to say I'm very pleased with this unit. My old machine was an Astoria AEP-2, which was great for an espresso shop, and the Expobar really feels like a scaled down version of a commercial machine. I can't imagine wanting or needing anything more. Okay, maybe another portafilter or two, and a Rancillio Rocky, and a better tamper...

Tim

 
There are more important things than espresso, I just can't recall what they might be.

Great review!  I particularly liked the comparisons to other machines in this class/category.  I use CG as a reference in making purchases so these comparisons make decisions easier.  I don't yet have the knowledge to make the kind of adjustments the author talks about doing (temperature changes) but more time on CG and I will.  One other thing, machine dimensions would be helpful, particularly height.

Some info that may be of use to Pulser owners. I bought a Pulser in the UK in May of 2005. It was "new old stock" and purchased from an importer that was setting up small coffee shops but had never been used. I have a small kitchen and was thrilled to find a machine this good that would fit beside my sink and for a decent price - GBP400 in total.

My Pulser came with a plumbed-in kit (which I have not used - London water would kill a boiler in a month) and 2 drip trays - one with drain and one without. I used the one with a drain and hooked up some piping to the sink. Works great, but the regular drip tray is pretty big anyway.

The OPV was set to about 14 bar, measured with a PF - mounted gauge. While adjusting that, I noticed that the OPV "overflow" had no return - it was just dumped in the drip tray. This is probably due to the plumbed-in setup (endless water supply) but I took the opportunity to add a return line into the reservoir. Note - make sure this is above the water line or you can siphon the tank onto the counter! Don't ask.

I have the tall feet and this works well as the drain line has to clear. I thought about switching to lower feet, but the Pulser has RivNuts at the rear which the feet screw into, and these are 8mm where most replacement feet are 10mm thread. So if looking for new feet, make sure they fit the threaded holes at thee rear. Front are just nuts and easily changed.

I have insulated the boiler from the reservoir with some ceramic balanket - there is not very much space (a very narrow machine) and it's tough to get the metal divider back in. This machine has no spring switch under the reservoir. The reservoir has a clear area at the front, and by totally removing the plastic window on the machine case, it was sort of visible. I then added a small submersible lamp (used in trendy aquariums) and that makes it simple to see the water level from 20' away. BTW - you can also put a clean colo(u)red ping pomng ball in the reservoir to help.

I also had a new drip tray screen made. The OEM screen is wire and small shot glases wobbled on it, so I had one made out of perforated alumin(i)um that works much better.

I've also added a "cool" steam wand (sourced from Australia) with a two-hole tip and that makes frothing a breeze. And the milk doesn't "cook" on the wand, which is great. Also got a set of Les Albjerg's wooden tamper/handle sets - very nice!

http://www.thortamper.com/cococombo.html

My only issue with the Pulser is that it randomly refuses to thermosiphon on its own. This means that some days, despite being on for an hour, the group is still cool. Running the pump will eventually get water out the head (maybe 20 seconds) and then all is fine the rest of the day. I have replaced the solenoid, checked for leaks but it still has this problem, which is easy enough to live with, but a bit of a mystery.

I invested iin an RO water filter setup since with 400 tds water here in London, I was having to buy Volvic to use for coffee. I figured out I would pay more for water in a couple of years than I pais for the machine, so I now add just a bit of tap water to get back to the sub-60 tds that is boiler safe.

The manual that comes with the Expobar from the manufacturer is a hoot and pretty useless. Frothing is called "strangling the milk". But if you look on CG and other sources, you will get instructions on setting up preinfusion and on the auto-backflush cycle.
