Andis Detailer

There’s a lot of love out there for Andis Slimline Pro Li, and I’ve got to say it’s fully deserved.

Call (972) 294-6087. However they don't cut nearly as close as any of my detailer or t outliners. Ive adjusting the blade probably a dozen times or more and I can. The Andis T-Outliner – The Final Cut Not surprisingly, the T-Outliner is right up there with the best trimmers on the market. Where it excels above the Outliner 2 (and many others) is in the details, literally. When you need to do an edge-up or detail, this is the trimmer you should turn to.

This neat little trimmer is solid for anything from necklines to light touchups or detailing work.

It’s also one of the lightest barber-grade trimmers. At only 0.3 lbs, it’ll never cause you any hand fatigue even on the busiest of days.

Let’s talk about it (check latest prices here). In particular, I’ll give you some advice regarding:

  • Slimline Pro Li vs Slimline Pro or Slimline 2

  • Comparison between Slimline Pro Li vs Wahl Detailer or Beret

  • What’s the difference between the Pro Li and the classic Andis T Outliner?

Excuse the leftover hair, but here’s our little Li-ion buddy after some hard work at the barbershop:

Now let’s get to the full review. Choose whichever section interests you the most.

New vs old:
Andis Slimline Pro Li vs Slimline Pro vs Slimline 2

Here’s the thing: Andis don’t really manufacture the older #32655 Slimline Pro. However, as some merchants still have it in stock, people have been asking me what’s up with these two.

Whatever the Pro does, the newer #32400 Slimline Pro Li does better. Highlights include:

Andis Detailer Cordless

  • A 2 hour Lithium-ion battery life, instead of the older NiMH with the Pros.

  • Faster rotary motor: 6000 strokes per minute against 5700.

  • D8 blade over the older, not as close-cutting D7 blade.

What about the Slimline 2, though?

Very similar conclusions. While the Slimline 2 trimmer has the same motor as the Pro Li, it suffers from two drawbacks:

  • The battery life isn’t as reliable and requires a longer charging time.
  • The blade isn’t a part of Andis’ D-series T blades. It’s not optimal for barber-grade edging or lineup work.

If you’re a professional, I’d definitely go for the Pro Li in this case. You need power and reliability, and the trimmer isn’t that much more expensive than the other two models.

Andis Slimline Pro Li

The best of the Slimline family. Longest battery life, best cutting blade and a 6000 SPM strong rotary motor.

Wahl’s competitors:
Slimline Pro Li vs Wahl Detailer or Beret

If you ask a bunch of barbers, there’s a good chance some of them will actually have both a Pro Li and a Detailer.

I’ve been a longtime satisfied user of the praised Professional Detailer too:

Its very compact size (just 5″) makes it one of the smallest high-end trimmers on the market. While not as lightweight as the Pro Li, it’s still only 0.43 lbs. Easy to work with and maneuverable for trickier areas like around the ears.

In terms of crisp lines, Detailers hit as good as the Pro Li. A big advantage: unlike the D8 blade, the opening under the Detailer blade isn’t as wide.

The Pro Li blade design allows for trimmed hair to fall right into that gap. Effectively this means you need to clean it more frequently compared to how Wahl designs their blades.

That said, the Detailer is corded and a bit noisier. Also, Slimlines work a bit better when zero-gapped.

There’s a cordless Detailer out too. It improves everything over the corded version, but costs a pretty penny as I’ve noted in my comparison of Wahl trimmers. As a 5 Star Detailer, it also features a wider T-blade which deals better with bigger surfaces and necklines.

Wahl 5 Star Cordless Detailer

Sharp and wide T blade for crisp lines and supreme neckline trimming. Expensive, but in a league of its own.

Andis Detailers

As for the Beret or the Sterling Mag…

These are Wahl’s quietest hair trimmers. The blade also has a softer touch. While not as good as the Pro Li for bulk trimming, these two are perfect for more sensitive areas.

Their silent operation really helps with kids, if you do kids’ haircuts or lineups. The finer teeth of the Beret, however, might stall with bigger volumes of facial hair.

Finally, the guards of the Pro Li are more diverse. The Beret attachments start from 1/8″, so you can’t really go comb-short with it as you can with Andis.

OK, now that’s the classic battle for those who want to stick to Andis trimmers only.

Make no mistake – the high-rated T Outliner is way more powerful.

First, it deals with an electromagnetic, not a rotary motor. This allows it to unleash 7200 SPM of pure trimming power compared to Pro Li’s 6000 SPM.

But there’s a dark side to that… heat-ups and weight. The T Outliner will turn hot if you work with it more than 10 minutes and it weighs double at 0.7 lbs.

Wahl T Outliner

Another thing that the T Outliner does better is its famous T blade. Those close-cutting blades cut sharper and form more precise, crisper lines whatever you decide to do. They heavily outperform the D8 blade of the Pro Li.

Additionally, the T-blade covers a wider area. You can branch out to better bald fade finishes this way.

Corded, heavier, heats up…But comes with more power and better blades.

What can you do?

First, you can opt forthe cordless T Outliner. While it has a slightly shorter battery life (100 minutes vs 2 hours), it’s basically lighter, mobile upgrade. Costs quite a bit, though.

Slimline Pro 2

Second, you can swap the D8 blade and put a T Outliner blade like this on your Slimline Pro Li. It might take some time and involve a bit of sweaty work, but it’s doable.
