Review: Way better than I expected! - I've waited a year and about 1000 splices to write this review. I have 13 years of experience using at least a dozen different machines. I originally bought this splicer as a cheap option for starting my business. Even though I own a used Fujikura 70S now, it sits in my office and I STILL use the SignalFire. I like the small case, though I'm way too tall to find the stool useful so it's in the garage on a shelf. The important thing to remember is that it's a little finicky and requires regular cleaning and calibration. the cleaver is the same way, pretty solid but requires maintenance and adjustment more than some others. With regular maintenance, it's been really reliable for me and my splices test out great. I would really like some sort of arm to close the heater automatically, rather than having to align the splice with 4 fingers and close it with a 5th but I have gotten used to it and it doesn't really bother me anymore. The other problem with the heater is if you let the sleeve fall to the bottom, it can pinch grooves into the sleeve but holding it while you close the heater solves that problem. I'd also be willing to pay a little bit more for a built in UI with a touch screen; I'm not a big fan of the app, though it works alright. On a scale of the best splice machines I've used, it's probably a 3.5 star machine (beating every INNO I've tried by a mile). The reason for 5 stars is the price to value ratio. Absolutely worth it. Overall, I'm very surprised and impressed with how functional it is at this price.
Review: Smooth Stripping and Reliable Splices - The built-in fiber stripper is much improved and works smoothly. The splices come out clean and reliable every time. Setup is quick, and the machine is easy to operate, even for longer jobs. The screen is clear, and the alignment is accurate, making the whole process faster. Definitely a solid upgrade that saves time and delivers consistent results.

## Features

- 【Faster Splicing & Heating】- Signal fire fusion splicer AI-20 is the fourth-generation optical fiber fusion splicer, it combines electric ONE-STEP fiber cleaver and fusion splicer as one, with 9-in-1 signal fire stripper. The AI-20 fusion splicing machine uses a powerful high-speed motor that allows fast 6 second splice time and 15 second heat time, continuous splice and heats about 240 times.
- 【 Automatic Delayed Return Electric ONE-STEP Cleaver】- Perfectly solves the problem of traditional mechanical one step cleaver back cutting scratching the fiber end face. The factory standard delay time is set to 0.5 seconds, and the adjustable range is 0.2 seconds to 2 seconds. ﻿The fiber splicer machine integrates optical fiber cleaver, waste fiber box and fiber cleaning brush which makes your operation more convenient. After placing the fiber, make sure that the fiber has passed the far right of the cutter, the lid is closed and automatically cut. (NOTE: PLEASE KEEP THE CLEAVER CLEAN WHEN USING IT, OTHERWISE IT WILL AFFECT THE ACCURACY.)
- 【Built-In Power Meter & VFL】- Using the latest core alignment technology with auto-focus and six motors. Effectively measure connection losses, verify continuity, and help evaluate fiber link transmission quality. OPM can be switch between the wavelength of 850nm; 1300nm, 1310nm, 1490nm, 1550nm, 1625nm,980nm,1270nm,1577nm and 1650nm. VFL can be switch between three states power: 15mW, 2Hz flashing and steady on mode.
- 【Clear LCD & Long Time Standby】- With 5-inch high-resolution screen, it is up to 320 times the focus magnifications when X/Y Axis displayed separately, 200 times focused magnifications when X and Y Axis dual display. 7800 mah high-capacity lithium battery, charging time ≤ 3.5 hours.
- 【Intelligent Interaction】- This splicing heating machine can be connected to mobile app, ten different languages can be switched like English, French, Russia, Italian, Portuguese, polish, Spanish, Thai, Arabic which is convenient for customers to use. You can check the data by your mobile phone and downloaded or output at any time, also the splicing records can be stored indefinitel.

### ⭐⭐⭐⭐ It was an exacellent machine while it lasted....review updated
*by C***. on June 20, 2023*

Excellent product for the price. Instructions were almost impossible to follow I found. That said, strip it, cleave it, insert it and DONE. The app on the phone is imperative to make any changes to default settings. Connecting with Bluetooth was hit or miss with my IPhone.....it would connect, then drop, then could not reconnect....That was certainly frustrating. All that said, VERY happy with this purchase. Once you get the process down, it's very simple to use. I've done 50 burns so far. UPDATE.. After about 250 burns I've run into some problems. The unit will no longer run on the battery alone: it needs to be plugged in order for it to stay turned on. As well, the fiber sleds are not bringing the strands close enough to get a proper burn. I can't seem to calibrate it. It's taking 6 or 7 attempts to even get the fibers welded and when they do, the are VERY delicate and high loss. For the price I paid, I got my money out of it. Rather than mess around further I'm just going to buy another unit.
