OK, they don't look that great in a photo. I'll admit that.
Having handled one and had a play, for the money they are good value. A bit of modding helps (longer stem for tall people, wider base to keep them stable) but the actual lens is quite good and the the lights work pretty well at getting the photons to bounce through the lens (rechargeable AAA test I think - we've got oodles of chargers, NiMH rechargables are recyclable and available in pound shops but we NEVER use them for some reason).
I'm having issues with reading part numbers from small components and for that, these will help.
