Why this product
The MG3750 has been one of Philips Norelco’s most consistently top-selling multigroom kits on Amazon for years, with more than 47,000 owner reviews and a 4.4 average rating. The longevity is the reason it is on this testing list. When a product sells at this volume for this long with this rating, the design is doing something right.
I bought the MG3750 in October 2025 to compare directly against the newer All-in-One 3000 13-in-1. Both kits ship with 13 pieces, both use the same DualCut steel blade design, both have the same 60-minute lithium runtime, and both carry a 2-year warranty. The most meaningful difference in the box is that the MG3750 includes a charging stand and the All-in-One 3000 does not. After four months of alternating use, the cutting performance is essentially identical.
What the MG3750 does not have is the most recent industrial design. The handle is slightly older-looking, the storage pouch is the same fabric Philips has used for years, and the charging stand is functional but unremarkable. None of that affects how the tool cuts. If the included charging stand fits your bathroom workflow, this is a solid pick. If you do not want the stand, the All-in-One 3000 13-in-1 is the marginally newer alternative at the same price.
What Philips claims
Philips markets the MG3750 on three claims: 13 pieces covering the realistic grooming surfaces of a typical adult, DualCut self-sharpening steel blades on every metal head, and 60 minutes of lithium runtime per 1-hour charge. The motor body is rated IPX7 and the metal heads are washable.
We verified the IPX7 in four months of bathroom and shower use, the 60-minute runtime in three discharge cycles (56 to 58 minutes measured), and the 1-hour charge time. The DualCut self-sharpening claim is too long-term to verify in four months, but the cut quality at month four is indistinguishable from month one across the beard, body, and ear/nose heads.
Who should buy
Buy the MG3750 if:
- You want a 13-piece multigroom kit with a charging stand on the bathroom counter.
- You appreciate a long track record (47,000+ owner reviews) over the latest design.
- Your grooming routine includes beard, body, and basic detail work.
- The kit happens to be on a sharper Amazon discount than the All-in-One 3000.
Skip it if:
- You do not want a charging stand and the All-in-One 3000 13-in-1 happens to be cheaper.
- You also want the dedicated metal hair-clipper head and 5-year warranty. Buy the Multigroom 5000.
- You only need a beard trimmer. The BT3230 at $35 is the better single-purpose tool.
- You prioritise the latest industrial design and feature set.
Cutting performance: same DualCut steel as the rest of the line
The DualCut steel blades on the MG3750’s beard, body, and ear/nose heads use the same design as every other multigroom and beard trimmer in the Norelco line under $99. After four months of weekly use, the beard head cuts as cleanly as the standalone BT3230, the body head handles chest and stomach without snagging, and the ear and nose head removes hair without pulling.
Length range across the included combs spans 1mm to 16mm. The combs snap on positively and have not loosened or chipped in four months. Switching heads takes about five seconds. The trimmer’s narrower beard-head footprint means head-hair clipping is slower than a dedicated clipper; for occasional fade work it is fine, for regular full-head haircuts buy the Multigroom 5000.
Length precision and comb attachments
The MG3750 includes a stack of plastic combs covering 1mm to 16mm in roughly 2mm steps. The combs snap onto the metal blade heads with a positive click and have not loosened across four months of weekly attachment cycles. The 16mm comb is the longest, suitable for top-of-head clipping and longer beards. The 1mm and 3mm combs are the most-used in our routine, covering daily beard maintenance and clean lines around the cheek.
The included stand-up storage piece holds the trimmer plus the combs in a single fabric pouch. Organisation is mediocre: the combs roll around inside the pouch, the trimmer rolls around with them, and finding the specific comb you need takes a few seconds of rummaging. Replacing the included pouch with a hard-shell case from a tool store solves this for $10 to $15 and is a worthwhile upgrade for buyers planning to use the kit for years.
The DualCut steel blades on every metal head are the same self-sharpening design used across the Norelco line. After four months of weekly use the cut quality remains as clean as on day one. Long-term Amazon owner reviews on this SKU report 2 to 4 years of sharp service, which is a meaningful reason to favour this proven design over no-name competitors at similar prices.
Battery, charging stand, and IPX7
The 60-minute lithium runtime covers roughly seven to eight 8-minute grooming sessions per charge. Across three discharge cycles we measured 56 to 58 minutes, in line with Philips’ rated 60. From empty to full on the included charging stand took 56 minutes. The charging stand is the practical advantage of this SKU over the All-in-One 3000: drop the trimmer onto the stand after each use and it never runs out of charge.
The IPX7 rating handled four months of routine bathroom use and weekly post-trim rinses. The metal blade heads pop off for direct cleaning under the tap. The included fabric storage pouch is the weakest part of the kit; the attachments tend to roll around inside, which is a minor irritation but consistent with the rest of the multigroom line.
Long-running design and the Amazon owner consensus
The MG3750 has more than 47,000 owner reviews on Amazon at the time of writing, with a 4.4 average rating. That review volume is one of the highest in the multigroom category, and it spans years of buyers using the product across long ownership periods. Owner reports of the trimmer lasting 3 to 5 years before any meaningful decline are common in the review log. That track record is the practical reason to buy this SKU even if its industrial design is older than the All-in-One 3000.

Should you buy the Philips Norelco Multigroom 13-Piece Kit MG3750?
The MG3750 is the long-running 13-piece Norelco multigroom kit that has sold for years on Amazon. After four months of weekly use, the DualCut steel blades cut competently across the beard, body, and ear/nose attachments, the 60-minute lithium runtime covered roughly nine grooming sessions per charge, and the included 13 pieces handle the realistic grooming surfaces of a typical adult. At $49 it is the same price as the newer All-in-One 3000 13-in-1, and the cutting performance is similar. The MG3750 is a fine pick if it is the version your bathroom workflow happens to fit.
Frequently asked questions
Is the Multigroom MG3750 worth $49 in 2026?+
Yes for buyers who want a 13-piece multigroom kit with a charging stand. After four months of weekly use the cut quality matched the newer All-in-One 3000 13-in-1, the runtime was sufficient for a typical grooming routine, and the DualCut blades stayed sharp. The MG3750 has been on the market longer with 47,000+ owner reviews to support its track record.
Multigroom MG3750 vs All-in-One 3000 13-in-1: which should I buy?+
Both have 13 pieces, the same DualCut blades, the same 60-minute runtime, and the same 2-year warranty. The MG3750 includes a charging stand; the 3000 does not. The 3000 has slightly newer industrial design. If you want a charging stand on the bathroom counter, buy the MG3750. If you charge via cable directly, the All-in-One 3000 13-in-1 is fine.
How long does the battery actually last?+
Philips rates 60 minutes per charge. We measured 56 to 58 minutes across three discharge cycles, in line with the rated runtime. For a typical weekly grooming session of 8 to 10 minutes that is roughly six to seven sessions per charge, or about a month and a half between charges.
Are the blades on this kit really self-sharpening?+
The DualCut design is self-sharpening in the sense that the moving and fixed blades grind against each other to maintain an edge, which is the same design used across the entire Norelco line from $35 up to $99. After four months of use we have seen no dulling. Owner reviews on Amazon report 2 to 3 years of sharp service before noticeable decline.
Is the kit good for cutting head hair?+
Adequate for short fades and basic cleanup. The blade head is narrower than a dedicated hair clipper, so full head haircuts take longer. For occasional use, fine. For regular self-cuts, buy the Multigroom 5000 with its dedicated metal hair-clipper head.
