Just a couple of minor niggles.
1. Pre cut hole for charging and changing SD card - I have the Sat Nav card so was constantly taking the sleeve off to change cards.
2. The unit has a recessed start button on the front of the unit. But the sleeve has a raised hard bubble. Sometimes when replacing the unit back into the supplied hard case it has switched the unit on and drained the battery. So a pre cut hole the same as the antennna hole at the back would be good.
I have manual cut the silicone sleeve to accomodate both these issues but it does look a bit messy. I would think the spec for changing any future sleeves would not be too costly. I would buy this upgraded sleeve if it was marketed.

hi,
Go to "Technical support forum" - "Adventurer 3500" - "Battery drainage", for a possible solution to your battery drainage problem.
