We have some i300c in our school equipment.  They are easy to use, but the screen like all pucks is small.  Also you must make sure that the water contacts are dried at the end of the dive so the computer will go to sleep and save your battery.  

The computer will go to sleep once the residual nitrogen has cleared which of course will be several hours and the water contacts must be dry.

The battery is user changeable, but you must use the tool provided to open the back door.  It's a little tricky, so best to check your battery before heading out and always have a spare at hand.

Aqualung, Oceanic, Sherwood and Genesis computers may look very similar and that's because they are all made in the Pelagic Pressure Systems factory in the USA.

Aqualung i300c shares the Oceanic Veo looks and technology

Acquired by Aqua Lung in May 2015, Pelagic Pressure Systems has had a long history of innovating dive instrumentation.  But with the extra funds put in by Aqualung, the R&D has improved as has the reliability of the computers.

Pelagic Pressure Systems is a designer and manufacturer of dive instrumentation for many of the leading brands in the dive industry today. Pelagic was founded in 1980 and is located near the Silicon Valley technology hub in the San Francisco Bay area, USA.
