Overall, a nice way to get little dabs of paste right where you want them. It is lightweight, even when loaded, and doesn't get in the way when applying paste in tight areas (under a microscope). I really like how you can hold it like a pencil: sandwiched between your thumb and middle finger, you can use your index finger to actuate the dispensing lever. You don't need to apply that much pressure to get it to go, but be careful that you watch out for pressure build up in the syringe, and release the piston before you put it down, otherwise a bit might creep out.
If I could change anything about this, it would really only be the dispensing lever. The lever can swing a total of about 25 degrees or so, but only 12 of those do anything. The other 12 degrees are just extra traversing space, and it is sort of bothersome. The fix would probably be to change the design of the little sheet of metal at the end of the lever that pushes the plunger rod foreword, but if you don't want to modify it yourself, find a stronger spring to replace the larger of the two, and that'll keep the lever from jiggling.
