Dr. Fox Magnifying Machine Reviews
Bricksfanz
“It may be a small set, but that shouldn't be it's flaws can't be highlighted. Although the barrel of the Magnifying Machine can be ‘zoomed' up and down just like a real microscope, this can only be done by moving the whole thing. It would of been great if a longer Technic... More pins was used with a additional gear dial on one or both of the outside of the microscope were used. So you could move it as you would a real microscope. Plus I'd have liked to of seen a Dr. Fox figure included instead of the glasses, even if it meant the set cost a couple of pounds more. Still its a very quirky little set and has some cool parts.”

“The Dr. Fox Magnifying Machine set offers a creative take on a life-sized microscope, complete with functional zoom action and a playful design. While it lacks practical use, it features unique elements like rare purple plates, bright bluish-green curved bows, and printed tiles for the Petri dish. The inclusion of cardboard Dr. Fox glasses adds a whimsical touch, but a Dr. Fox figure would have been a more compelling addition to enhance the set.”
