Review: Splice well - Came new and intact. Splices very well without dB losses. The case it came in is very efficient and functional with a seat.. I would recommend it.
Review: Works Great! - I was worried how this would work for the price but with over 300 splices so far, not one problems at all. Great Price, Great Splicer. I would look into a better cleaver but it still works fine.

## Questions & Answers

**Q: Does this come with the heatshrink stainless steel rod reinforcement sleeves? Sorry, I don't know the propper term for them.**
A: Splice tubs....and unfortunately no, you'll need a pack of 60mm splice tubs when you buy the fusion splicer, other than alcohol you'll have everything you need to splice some fiber

**Q: All my fusion splices under a visual fault locator have a little red light bleeding out from splice. Is this normal?**
A: It’s most likely the quality of your sleeves. I use AFL 60MM. My unit shrinks on tight No bleed out the ends.

**Q: Will this splicer do Single mode and multimode splicing?**
A: Yes

**Q: comes randomly!  What does that mean?  Water proof, dust proof and fall proof?  seems like a high bar to meet.  Humanized toolbox?  what is going on?**
A: Thanks for your interests in our products dear.
Comes randomly refers to the difference between the original version and the upgraded version of the heating tank, except that the other parameters are the same.
Hoping my answer is helpful to you and looking forward to your purchase.
Sincerely
