To give a better review I need to break it down into pros and cons, with a little explanation in between. Pros:
It's extremely inexpensive in it's class.
It easily set every size in aluminum that came with the tool*
Mandrels for this tool can be found on Ebay dirt cheap, even with added shipping
from the U.K.(Ref: Laser Tools 0979 Nut riveter)
*Most of the instructions show the rivet nut being screwed so far up the mandrel that it is nearly impossible to to get a grip on the tool. If there is room, back the nut down until the mandrel threads are flush with the bottom of the rivet nut.
You can always give the nut another crank if it isn't fully mushroomed. Remember that this tool is not a Pop riveter. There is some skill required to learn to feel when a nut is set. You need to test nuts on material that allows you to see the blind side so you have an idea of what your squeeze is doing in relation to it's feel.
Cons:
The directions are a one-way road to failure in most cases.
The Knurled portion that allows you to thread the mandrel is a bit undersized, especially when trying to thread on 1/4-20 nuts of less than excellent quality.
Some useful advice:
Keep the mandrels lubed and free of aluminum remnants so your nuts thread on smoothly.
Tighten the mandrels well so they don't come undone while threading on the nuts.
As far as quality goes, every major manufacturer of this kind of tool(I've dealt with Marson/Alcoa, AVK, Avdel, Pop) is plagued with complaints of the smaller mandrels breaking, and in every case I've been exposed to that appears to be from a lack of proper instructions on the OEM's part or the end user just sqeeezed the tool well after the nut was properly set. FYI, the handles, in many cases, do not need to be fully cranked down. Once you feel that a nut is no longer "flowing", stop.
