I bought one of these 'scope kits a few months ago now - the one with the SMD components already soldered. Assembly was straightforward apart from the slide-switch leads which needed a good scrape/clean before they would take solder (real stuff with lead in it !)
More recently, I noticed that a laser-cut acrylic case was available for the unit so I decided to get this as an upgrade. It cost about £5 when I got it.
It is a flat-pack type and whilst nice, it does have a few 'niggles' which I thought I'd mention.
It is not supplied with any spacers, only nuts and these need to be correctly adjusted to set the gap between the top half and the main pcb without over stressing the board.
The spacing is quite critical if the switch extensions are to operate correctly and the ideal spacing is 9mm. The supplied M3 nut adjustment is not ideal and at the time, I did have a look for suitable spacers but didn't find anything available for a reasonable price - until last week when I saw these and so ordered some 8mm ones, this being closest. They are made from aluminium, red anodised and are M3 threaded.
With the addition of a few M3 washers the unit was re-assembled as shown in the pictures.
Unfortunately the rear piece holes don't quite line up correctly so you'd either need to ream the hole slightly or use a long-reach DC power plug for the unit.
BTW, these is no 'wiggle room' with these items as they're made to very fine tolerances.
Overall I think this a worthwhile add-on for the oscilloscope.
