Wire Terminals Crimping Tool Kit, Preciva AWG20-10/0.5-6mm²Insulated Ratcheting Crimper Tool with 350PCS Insulated Wire Connectors

The crimper is a very well made and a functional tool. The included terminals are a bit thin and probably wouldn't work at the different wire gauge amp ratings. I didn't buy it for the terminals so not really disappointed. Have used it with some heavy duty (marine type) connectors and worked perfectly.Still a good value and is indeed easy to use.

I use high price crimpers at work, but I didn't want to pay $100+ for just a set of crimpers for home use. This package came with a good assortment of terminals and the crimpers exceeded my expectations. I would recommend this product.

Locking mechanism is a pain sometimes, be careful to use the right size slot otherwise the lock will drop in and you can't open it. (you have to squeeze it and pop out the lock). Otherwise it has a nice grip and good pressure on crimp.

The media could not be loaded. I needed to replace a blue connector on an adapter that I crimped on one end and I needed to remove the connector. I installed a led hood light on my vehicle. The mini low profile adapters are costly if you have to keep replacing them. I decided to just replace the blue connector instead of the whole adapter. This gadget did the job. It is kind of heavy but it's well made. I had to use both hands to crimp. It's pretty large for female hands. It comes with 370 different connectors for various connections. It's worth the money and for the small job that I bought it for, I was satisfied. I'm sure it will come in handy knowing me...I'm always finding something to install or fix!

I have used the cheap HF wire crimpers forever and they never do a great job, so I wanted the get the ratchet style. These work great and I haven't it had any wires come lose since I started using these. The fact that they come with a bunch of connectors is a great bonus.

Works great! Nice smooth motion, smashes big wire easily.

Preciva Wire Terminals Crimping Tool Kit (USRC50371), I feel a duty to warn others. The experience of using this product was bad enough. Realizing why I bought it—because of suspiciously glowing reviews—was worse.Let me break it down:1. The Crimper is Fundamentally UnreliableThis is advertised as a “ratcheting” crimper suitable for AWG 20–10 insulated terminals. In practice?• The ratcheting mechanism is inconsistent. Sometimes it engages; sometimes it doesn’t. That defeats the entire purpose of buying a ratcheting tool for repeatable, reliable crimps.• I had to force the jaws manually on multiple attempts just to get a crimp to hold. There’s no smooth action. No mechanical precision. Just clunky resistance.Even worse: once it does ratchet, the release mechanism can lock up or feel sticky—leaving you mid-crimp, stuck and fumbling.This is not a small inconvenience—it’s a deal-breaker if you’re working on live circuits, automotive wiring, or anything where speed and precision matter.2. Connectors are Substandard—Dangerously SoLet’s talk about the included 370-piece terminal set.They’re astonishingly cheap. The insulation is paper-thin, the metal barrels feel weak, and I had multiple wires pull right out of supposedly “fully crimped” terminals using light force. These aren’t just low-quality—they’re unsafe.In one case, I used a red (22-18 AWG) terminal, gave the wire a light tug, and it popped out with zero resistance. That could be a fire risk if you used this on anything that carries current.3. The “New Handle Design” is a Marketing IllusionThis was one of the main reasons I clicked “Buy Now.” But truthfully? The handle is no improvement over the standard $10 crimpers at the bottom of a parts bin.• Supposed “anti-slip” grip? It’s slick plastic with minimal texturing.• The handle angle is awkward, and if you’re working more than 5–10 crimps in a row, your hand will hurt. There’s no real ergonomic consideration here, just generic molded grips.It screams cheap tooling rebranded for Amazon.4. Fake Reviews? Something Doesn’t Add UpLet’s look at the review profile. This product has hundreds of 5-star ratings and almost no negative feedback. That’s statistically improbable for a budget electrical tool.What do the glowing reviews say?• “Great tool”• “Worked fine”• “Love it!”They’re all vague, surface-level, and repetitive. Few mention actual usage details, wire gauges, terminal quality, or even what they used the tool for. That’s a massive red flag. The negative reviews, on the other hand, are rich in specifics—failures on the red gauge, tool jamming, terminals breaking. That contrast is telling.It doesn’t take a conspiracy theorist to see this looks like a review-padded listing—something that happens more and more on Amazon, especially for inexpensive tools made overseas, where sellers aggressively boost product visibility with incentivized or paid reviews.5. Return Experience Was a PainI decided to return it the same day it arrived. But the packaging is molded and tight—getting everything back in was frustrating. Amazon accepted the return, but I lost time, had to pause the job I was working on, and ended up borrowing a Klein from a coworker to finish.Final Thoughts: Don’t Risk ItIf you’re a hobbyist working on a small project and don’t mind possibly wasting a few hours troubleshooting loose crimps or bent terminals—maybe you’ll get by. But if you’re a technician, electrician, auto tech, or just care about reliability? This tool should not be anywhere near your toolbox.There are real brands out there—Klein, IWISS, Engineer Inc.—that make dependable crimpers for not much more. With this kit, you’re not saving money. You’re throwing it away and putting your wiring at risk.⸻Summary• Poor ratcheting performance• Weak terminals, prone to failure• Uncomfortable, awkward handle• Highly suspect review patterns• Not worth the risk for real workI’ll never trust this brand again, and I strongly advise others to skip it too.

Tools is robust but doesn't feel like too high quality. It is OK for the price and will do for most DIY and hobby wiring jobs.
