DavecUK I supported them through the Kickstarter and here are a couple of things to highlight:
1- It is using a brushless DC Motor. Not an induction motor.
2- It has an RPM range of 200-1000 initially but was upped to 200-1200 rpm range.
3- It uses a belt. But, It’s a toothed belt. I hate belted grinders since most use the smooth type of belts but the deva is using a toothed belt that will help in the torque conversion.
4- The most interesting part is the mailable copper piece that they implemented in aligning the burrs. Gonna post a YouTube video on it below.
5- The battery is replaceable on site. No need to ship it and they are using a LiPO battery which I approve of instead of 18650s. The Lipos will give you the DC current all the way down to the end of the charge while the 18650s will be decreasing voltage through out the charge.
6- My guess why they went with the battery option is reduce the need for certifications and electricity needs all over. (50/60hz 110/230v compatible worldwide) while also giving the option of having it as a portable unit.
7- The thing that won me completely was the honesty during the kickstarter, They were transparent to a point which is rarely found in any crowdfunding exercise.
A couple of pics:
As a rotating equipment engineer by day… I get an eyegasim once I see alignment such as this:
In addition, He is checking alignment of the shaft at the end of shaft…. not like some other companies that check it at the midpoint of the shaft and giving an illusion of decent alignment. 30 micron reading at the middle can be between 50 to 70 at the end of the shaft.
Pic of the belt (Clever means of using the upper wooden part to hide it and most likely a design choice to help in replacement without a complete dismantling if it needs replacement):
Rarely would see videos of maintenance work be posted 3 months prior to delivery:
Cleaning and replacement of burrs with how to align it:
Replacement of the battery:
1- Small Design.
3- Compatible with the most used home burrs 64mm burrs (They confirmed compatibility with SSP burrs but approved SSP HU for espresso and found SSP MP to be to slow in grinding espresso). They also confirmed that the new SSP Cast are compatible on Instagram but no news yet if it will fit espresso also or just filter.
4- Price is extremally good for what you get.
1- Reliability is unknown at the moment.
2- It’s a kickstarter with a pandemic so there was some delay in shipping. 3 Months delay is nothing to some other kickstarters… There is one with two year delay.
3- It is battery powered so the battery will die sooner or later but replacement seems to be easy.
4- It has maximum dose of 30g (which is fine for home espresso use) but some won’t like it for filters especially for those who usually grind 50g. They stated you can keep feeding it but that’s an extra workflow.
Waiting for my unit to be shipped to abu… err… use for a awhile before giving full feedback.
I am smelling a very good alternative to the niche for home use if you are into flat burrs.
