Just purchased the Amscope SM-4-TPZ Trinocular zoom and boom. It arrived today and I have used it already for a few hours.
First off, my order was a special order so that I had to call Amscope directly for the order. They were very kind, helpful and patient to explain everything regarding my order. They then confirmed with me exactly what I wanted and took great care to make certain that all was in order for the purchase. They sent a confirmation email and an email with the tracking number. The boxes arrived next day UPS.
Everything arrived today as expected. Well packaged, no damage, all components were NIB factory. It took me about 20 min. to set everything up and start using the equipment.
First light of the scope was awesome. The optics have great clarity. I tried out the 20x oculars along with the "included" .5x and 2.0x barlows. All performed well except that the 20x oculars aren't as crisp as the 10x oculars?? It is not a vignetting issue but more of a light gathering issue. The zoom is smooth, focus and all performed splendidly. Manufacturing appears to be high quality and even little things, like set screws, have nylon tips to keep from damaging metal parts.
The entire scope is metal framed unlike the Leica system which was plastic. All around it gives the look and feel of an expensive Meiji scope.
I have previously owned a Leica GZ6 with flex arm and gooseneck halogen lighting. I used that system for about 8 years and it performed well. I didn't like the lighting because it was a hassle to set up.
The entire Amscope system including LED Ring Light, 20x oculars, BBB boom stand, and FR-GA3 focus ring, was about $900 whereas the old Leica System was $3000! . I was a bit reticent of a $900 microscope at first, but now, I am very happy with it. You definitely get your moneys worth and some!
For those contemplating an Amscope, I am pleased offer a positive recommendation. The Amscope people were patient, helpful and provided a great purchasing experience with no hassles or drama's.
