Quick Answer
Research summary
If you trim often enough that line management becomes a recurring annoyance, the EGO Power+ 16-inch String Trimmer with LINE IQ is easier to justify than a basic cordless trimmer. The big reason is simple: its LINE IQ system and 16-inch cutting width are meant to reduce manual line adjustment and help cover more ground per pass.
The trade-off is also straightforward. This model is positioned as the heavier, pricier choice versus simpler cordless options, so it makes the most sense for frequent yard users rather than someone who only cleans up a very small yard now and then.

This is a RESEARCH-BASED REVIEW, which means the goal here is not to repeat marketing copy but to answer the buying question as clearly as the available evidence allows. For this model, the decision mostly comes down to whether automatic line management is valuable enough in your yard routine to outweigh added heft and cost.
That makes the EGO ST1623T a fairly specific kind of buy. It is not automatically the best choice for every homeowner. It is a better fit for people who trim regularly, deal with enough edge length or recurring overgrowth to care about workflow, and want strong cordless power without stepping down to a more basic feed system.

What matters most with this trimmer
The clearest reason to consider this model is its combination of LINE IQ automatic line feeding and a 16-inch cutting swath. In practical terms, that matters more for frequent maintenance than for occasional touch-ups.
- LINE IQ is the headline benefit. If your current trimming routine involves bumping, checking, or otherwise managing line feed more than you would like, this feature directly targets that friction.
- The 16-inch width helps with coverage. A wider cutting path can make routine trimming feel more efficient, especially around longer fence lines, beds, borders, and larger yard perimeters.
- It is aimed at stronger cordless performance. That is part of the appeal for buyers who want a battery-powered weed eater that feels more serious than entry-level options.
Where many reviews go wrong is treating those points as universal advantages. They are not. They matter most when you trim often enough for small efficiency gains to add up. If your yard care is light and infrequent, convenience features can be nice without being worth the extra bulk or spend.
Who it makes sense for
Best for
This trimmer fits frequent yard users who want automatic line management and strong cordless power. That buyer is likely to notice the convenience benefit because the tool gets used enough for line-feed interruptions to become irritating.
Probably a good fit if:
- You trim regularly through the growing season.
- You have enough lawn edge, beds, fence line, or recurring cleanup that workflow matters.
- You want a cordless string trimmer that prioritizes cutting coverage and reduced line fuss over minimal weight.
- You already like the idea of staying within the EGO platform and want a more feature-forward trimmer rather than the simplest option.
Skip it if:
- You only edge a very small yard occasionally.
- You care more about a lighter, simpler tool than about automatic line management.
- You do not mind a more basic feed approach and would rather avoid paying for convenience features you may barely use.
If you are in that lighter-duty camp, a simpler EGO option may make more sense. The closest internal comparison is the EGO Power+ 15-inch String Trimmer with POWERLOAD, especially if you are deciding between convenience features rather than between brands.
Main trade-off: convenience vs weight and price
The most important buying trade-off is not complicated: this model offers more convenience, but that convenience does not come free. The known downside is that it is heavier and pricier than basic cordless trimmers.
That matters in two ways.
- Longer sessions may feel less forgiving. Even without leaning on unsupported numbers, it is fair to say that added tool weight tends to matter more the longer you use it and the more angles you trim around.
- The value case depends on frequency. If you trim a lot, the reduced line-management hassle can be worth paying for. If you do not, the premium is harder to defend.
So when buyers ask, Is the EGO Power+ 16-inch String Trimmer with LINE IQ worth it?, the honest answer is conditional. It looks most sensible when the time-saving and interruption-reducing parts of the design match your actual routine. It looks less sensible when your trimming needs are light enough that a simpler model would already feel easy.

How it compares with EGO’s 15-inch POWERLOAD model
For many buyers, this is the real fork in the road. If you are already shopping EGO, the choice may not be between this model and a random competitor. It may be between this LINE IQ trimmer and the brand’s 15-inch POWERLOAD version.
Based on the available facts, the cleaner way to separate them is this:
| Question | Lean toward ST1623T LINE IQ | Lean toward 15-inch POWERLOAD |
|---|---|---|
| What bothers you more? | Manual line adjustment during trimming | Extra size, weight, or cost |
| What kind of yard use? | Frequent trimming where workflow adds up | Lighter or more occasional maintenance |
| What matters most? | Automatic line management and wider coverage | A simpler setup within the same brand family |
If that sounds like your decision, our review of the EGO Power+ 15-inch String Trimmer with POWERLOAD is the most relevant next read.
This is also where some buyers overestimate the value of a 16-inch cutting swath. Wider can be better, but only if you are trimming enough area for that extra coverage to matter week after week. On a very small yard, the difference may not change your experience much.
Bottom Line
The EGO Power+ 16-inch String Trimmer with LINE IQ is easiest to recommend to people who trim often and are willing to accept a heavier, more expensive tool in exchange for less line-management hassle and broader cutting coverage. That is the core value proposition, and it is a sensible one for the right yard and the right routine.
If your yard work is occasional or minimal, this may be more trimmer than you need. In that case, paying extra for LINE IQ and a 16-inch swath is harder to justify, especially if a lighter or simpler model would already get the job done.
FAQ
Is the EGO Power+ 16-inch String Trimmer with LINE IQ worth it?
It can be, but mostly for frequent yard users. The strongest case for it is reduced manual line adjustment combined with a wider 16-inch cutting path. If you only trim occasionally, the extra weight and higher price are tougher to justify.
How does LINE IQ work on the EGO ST1623T?
At a buyer-decision level, LINE IQ is the feature intended to reduce the need for manual line adjustment while trimming. This article avoids going deeper than that because detailed operating specifics should be confirmed against the current EGO manual and product documentation.
Does LINE IQ actually reduce manual line adjustments?
That is the main reason to consider this model. The known strength attached to this trimmer is that LINE IQ reduces manual line adjustment, which is most useful for people who trim often enough to notice that friction on simpler trimmers.
Is the EGO ST1623T too heavy for longer trimming sessions?
The main caution is that this model is positioned as heavier than basic cordless trimmers. Whether that feels like too much depends on your tolerance for weight, your yard size, and how long your sessions usually run.
Who should buy the EGO 16-inch LINE IQ trimmer?
Buyers who trim frequently, want strong cordless power, and place real value on automatic line management are the clearest match.
Who should skip this trimmer?
If you only edge a very small yard occasionally, this is probably more tool than you need. A lighter or simpler trimmer is likely the better fit.
Is a 16-inch cutting swath better than a 15-inch trimmer for home use?
It can be better if you regularly trim enough area for the wider path to save time. For smaller, lighter-duty yards, the difference may not be meaningful enough to drive the purchase on its own.
Is this a good choice if you already own EGO batteries?
Potentially yes, because platform buyers often get more value from staying within one cordless system. That said, exact battery compatibility details should be confirmed in current EGO documentation before buying.
