Not with that unit in particular... but I have a whole bunch of experience with other stuff made by John Oram [none of it good].
This "Trident" isn't the 'real Trident'... the 'real Trident' was started by Malcolm Toft and Barry Porter, two brilliant engineers... John Oram was a hiring mistake they made a few decades ago who ended up figuring out how to get the rights to use the Trident name.
I would be very wary of his product if I were you.
