Update (12/29/21): Heats up really quickly (as advertised), and the LED for the power button changes from RED to GREEN (see pics). Summary: I have had rotary tools long enough to remember when the first real accessory for a Dremel was the extension shaft. This is similar in that you have relocated the power source away from the part that you hold, resulting in a lightweight tool. The Worx Maker-X is a very convenient system, especially when you pair it with a regular sized brushless drill (listed below). Observations (glue gun): This mini-glue gun is a great addition, especially when using around the yard, where a 120V AC line would require an extension cord. The Maker-X line powers up quickly (e.g. the soldering iron), so I expect this glue gun to heat up fairly quickly. Conclusion (glue gun): At $30, rating this 5-stars, highly recommended, along with the rest of the Worx Power Share 20V line. The rest of this review is for the previously reviewed WX739L Rotary tool combo (there is video in the link below): https://www.amazon.com/review/R3HSAXMQJGSDVS/ref=pe_1098610_137716200_cm_rv_eml_rv0_rv Observations (maker-X system): 1) To test the rotary grinder (Dremel equivalent), I used the included 3/4" cut-off wheel, and cut a 1" section off from a 3/32" thick curtain rod bracket. Additional detail in that review. 2) Next I looked at the Angle Grinder. The 2" disc should be sufficient for most small tasks, and would excel at bolt/round stock cut off. I like that the motor is brushless, as that is then newest technology, which makes for more efficient and cooler running. You can really dial the speed down very slowly, which I showed in the video. 3) Lastly, I tried the soldering iron. Having soldered things just about my entire life, I was really looking forward to this; however, the temperature seems very low, relative to what the digital readout indicated. It does heat up quickly, and adjusts back down relatively quickly. I need to test this further, so for now I'm rating it fair. One thing to note, you'll probably need to increase the heat much higher than indicating. Recommendations: 1) These systems of tools really makes economic sense when you have many of them. This MakerX combo has the rotary tool, angle grinder, and soldering iron, and they also offer an air brush. I'm sure they intend to release more tools. The 20v Power Share is also compatible with many Worx 20v tools also. The heat gun is the only one sold separately, not as part of any combo. I intend to buy the mini heat gun; the reviews are fair, not great, but I would much rather use a mini heat gun than a lighter to shrink heat wrap. 2) For the angle grinder and soldering iron accessories, I used a 2-compartment Sistema container (link below), and added some foam to hold the bits from rattling around; I think it turned out really well. Drops right inside the bag, and all the little bits are there at your fingertips. Pros: Good fit & finish; brushless motor (rotary and angle grinder); 20v Power Share family of tools; includes a tool bag. Cons: A bunch of warning & caution stickers; soldering iron isn't super hot. Conclusion: At $170 for this set, I rate this 5-stars, and I would recommend this WX991L set over the smaller/lower cost offerings (like the rotary only for $100). Spend a little time to see which kit would suit your needs and budget.
