Fix it or throw it away? That has always been the dilemma when confronted with a broken part. The only reason why you would want to repair it is obviously cost-driven as it's often cheaper to repair plastics than it is to replace it. The thing to remember is the repaired part will never be as strong as a new replacement part and as long as it's a non-load-bearing component, it should be fine to repair it.
The Visbella demo kit we reviewed has the same formulation but is slightly different in terms of packaging than the ones we sell in our stores.
So with that out of the way, today we're looking at the effectiveness of the Visbella Speedy-Fix. Available in three different colours, cleargrey and black, to suit your applications. The Chinese adhesive firm claims a fast 7-second bond but we find that it only fully cures overnight at room temperature.

Putting two together.
Speedy-fix this is not: The two-parts formulation means a lot of juggling and requires a pair of steady hands.
Unlike standard two-parts epoxy or super glue-like (cynoacrylates) adhesives, the Visbella Speedy-Fix system is a bit more cumbersome as you have to first apply the powder before actually applying the cynoacrylates-like liquid. We find this process really messy and time-consuming and unless you have ample working space and steady hands, you're bound to make a mess of the entire repair. 

We suggest grinding a V-goove and temporarily joining the two parts together with either masking tape or cellotape. The masking tape or cellotape will also act to prevent the powder from falling out the other side. Also, it goes without saying that two surface to be bonded needs to be clean and roughen up for the pellets to fill and expands as it cures.

For a cleaner repair, you can still clean up the excess powder prior to applying the cynoacrylate liquid but that gets tricky in tight spots unless you have a makeshift vacuum hose with a straw-like attachment. Even then you risk bumping the repair area and knocking the powder out.

Why the V-groove?

While roughening up the surfaces to be repaired should suffice, the problem is getting sufficient powder to actually bond the two parts. The V-groove allows enough of the powder to melt and bond the two work pieces together as well as also allowing the powder to 'sit' in place until you're able to drip the liquid on it.
Grinding a V-groove not only allows the adhesive somewhere to "bite", but also allows for a stronger repair as the resin-like powder builds up. You can easily sand away the excess once cured. The "epoxy ring" was the leftover epoxy from the manufacturer that didn't quite held up.
The AA-powered EZ Engraver we carry works surprisingly well for this V-grooving task - you can even rest your finger on the shaft to slightly slow it down for better control in tight spots. However if you require a little bit more power or do a lot of fine hobbyist work or repairs, you might want to consider getting a Dremel rotary tool.

As a side note, while Visbella calls it a powder but it is actually made up of tiny resin-like pellets that dissolves and fills up the gaps between the parts - forming a very strong and hard bond to the pieces that it comes in contact with.

While Visbella actually demonstrated in their YouTube videos that their cynoacrylates-like adhesive can be used on its own, we find that its less viscous than super glue and doesn't really work on its own. Depending on the materials, your mileage might vary.
The resulting repair was strong enough to be usable even in this inflator pump collar repair. Note: The V-groove.
Overall, we find the Visbella Speedy-Fix strong enough to bond most rigid plastics and when applied properly, it proves strong enough to be usable. The catch is you still will have to deal with the clean-up process, i.e., de-burring and sanding, once the Speedy-Fix has set overnight before painting or putting the repaired parts back into service.

CT Hardware Top Tip: For car bumpers or motorcycle fairing crack repairs, you should also drill a hole at the end of the crack line to stop it from further spreading - as silly as it sounds, it actually works! Don't worry, you can fill and sand the holes you've drilled with the Visbella Speedy-Fix prior to putty and paint.
