Philips Norelco Multigroom 13-Piece Kit MG3750 Review (2026)

Why you should trust this review

I bought the MG3750 at retail specifically to compare it head-to-head against the newer All-in-One 3000 13-in-1. Philips did not provide it and had no involvement in this review. I have used it weekly for four months, alternating with the 3000, which is exactly the kind of direct comparison a shopper trying to choose between the two actually needs.

This SKU is worth taking seriously precisely because of its longevity. It has been one of Norelco’s top-selling multigroom kits for years, with more than 47,000 owner reviews and a 4.4 average rating. When a product sells at that volume for that long with that score, the design is doing something right, and the long ownership record in the review log is real evidence the cutting hardware lasts.

How we evaluated

I used the MG3750 across the realistic grooming surfaces it is built for, beard, body, and ear and nose, switching heads as a normal routine would. I verified the IPX7 motor body through four months of bathroom and shower use and weekly post-trim rinses, measured the battery across three discharge cycles, timed a full charge on the included stand, and tracked cut quality month over month to see whether the DualCut blades held their edge.

This is real grooming evaluation, not a spec recital. The questions I cared about are an owner’s: does it cut cleanly across all the attachments, does the battery match the rating, does the kit survive water, and is it meaningfully different from the newer 3000 that sells at the same price.

Cutting performance across the attachments

The DualCut steel blades on the MG3750’s metal heads use the same self-sharpening design as every other trimmer in the Norelco line, and that consistency shows. After four months of weekly use, the beard head cuts as cleanly as a standalone beard trimmer, the body head handles chest and stomach without snagging, and the ear and nose head removes hair without pulling. The blades grind against each other to maintain an edge, and at month four the cut quality is indistinguishable from day one.

The 13 pieces genuinely cover the grooming surfaces of a typical adult, with combs spanning 1 to 16 mm in roughly 2 mm steps. The combs snap on with a positive click and have not loosened or chipped across four months of attachment cycles. Switching heads takes about five seconds. The one honest limit is head-hair clipping: the beard-head footprint is narrower than a dedicated clipper, so full haircuts are slower. For occasional fade work it is fine; for regular self-cuts, a kit with a dedicated hair-clipper head is the better tool.

Battery, charging stand, and IPX7

Philips rates 60 minutes per charge, and across three discharge cycles I measured 56 to 58 minutes, right in line with the rating. For typical 8-to-10-minute weekly grooming sessions, that works out to roughly six to seven sessions per charge, or about a month and a half between charges. A full charge on the included stand took about 56 minutes.

The charging stand is the defining practical advantage of this SKU over the All-in-One 3000, which does not include one. Dropping the trimmer onto the stand after each use means it is always topped up and never dies mid-trim, which is genuinely convenient on a bathroom counter. The IPX7 motor body handled four months of routine bathroom use and rinsing without issue, and the metal heads pop off for direct cleaning under the tap. Water is not a concern with this kit.

Build, storage, and the older design

The honest weaknesses are about feel and design rather than function. The plastic body is light and reads as budget-tier; it does not have the substantial heft of a premium trimmer. And because this is a long-running SKU, the industrial design is older and less ergonomic than Philips’ 2024-and-later models, so the handle looks dated next to the 3000. None of that affects how it cuts, but it is worth knowing if aesthetics or grip comfort matter to you.

Storage is the other soft spot. The included fabric pouch is mediocre: the combs and trimmer roll around loose inside, so finding the specific comb you need takes a few seconds of rummaging. It is a minor irritation consistent with the rest of the line, and buyers planning to use the kit for years can fix it cheaply with a hard-shell case from a tool store, which is a worthwhile upgrade.

Who should buy the Philips Norelco MG3750?

Buy it if you want a versatile 13-piece multigroom kit with a charging stand on the bathroom counter and you value a long, proven track record, 47,000-plus owner reviews, over the latest design. Buy it if your routine spans beard, body, and basic detail work, and especially if it happens to be on a sharper discount than the All-in-One 3000. For a do-everything starter kit, the cutting performance and the always-charged stand make it an easy recommendation.

Skip it if you do not want the stand and the All-in-One 3000 13-in-1 is cheaper, since the cut quality is essentially identical. Skip it if you also need a dedicated metal hair-clipper head, where the Multigroom 5000 is the better buy. Skip it if you only need a beard trimmer, since a single-purpose model is the smarter spend. And skip it if you prioritize the newest industrial design and feature set.

The verdict

After four months of weekly use alongside the newer 3000, the MG3750 proved that its years on the market are earned. The DualCut blades cut cleanly across every attachment, the battery matched its rating, the IPX7 build shrugged off water, and the included charging stand is a genuine daily convenience. The older industrial design, light plastic body, and so-so storage pouch are the honest trade-offs. If the charging stand fits your workflow, this long-running kit is the versatile multigroom I would recommend.
