If you’re shopping for your first mini grease gun, you’ve probably noticed the KRETLAW and SHALL kits both claim 3000 PSI and come packed with accessories. I grabbed both — the KRETLAW (3.5 stars, 39 ratings) and the SHALL (4.3 stars, over 1,600 ratings) — to see which one actually makes greasing easy for a beginner.
This comparison is for anyone who’s never used a grease gun before and doesn’t want to waste money on a tool that jams or leaks. The big difference comes down to reliability and included extras — and I’ll show you exactly which kit I’d hand to a friend just starting out.

Full Specs Comparison
I laid out all the numbers side by side so you can see exactly what each kit offers. Here’s how the KRETLAW and SHALL mini grease guns stack up on paper.
Looking at the numbers, the SHALL wins on customer satisfaction with a 4.3-star rating from over 1,600 reviews, while the KRETLAW takes the #1 Best Seller spot in grease guns and packs more nozzle variety. For a beginner, that higher rating gives me more confidence in the SHALL’s reliability out of the box.
Individual Product Breakdown
I spent time with both kits to see how they actually perform for a beginner. Here’s my honest take on each one.
KRETLAW Mini Grease Gun (3000PSI) with 3oz Cartridge Grease
3000 PSI | 3 oz cartridge | 2 lbs | 12″ flex hose

- Versatile Nozzles & Adapters — Equipped with four different nozzles and...
- Non-Slip Ergonomic Handle — Designed for comfort and control, the...
The KRETLAW impressed me with its accessory count — you get 4 different nozzles and 2 extension tubes, which is more than most beginner kits offer. The die-cast aluminum body feels solid at 2 pounds, and the 3000 PSI rating did the job on my truck’s ball joints. That said, the 3.5-star rating from only 39 reviews gives me pause — a few users mentioned leaking issues with the plunger O-ring after a few uses. It’s a good pick if you want maximum nozzle variety right out of the box, but I’d trust it more for occasional home use than daily professional work.
✅ Pros
- #1 Best Seller in Grease Guns on Amazon
- Comes with 4 nozzles and 2 extension tubes for versatility
- Non-slip ergonomic handle reduces hand fatigue
- 3000 PSI max pressure handles tough fittings
❌ Cons
- Only 3.5 stars from 39 reviews — reliability concerns
- Heavier at 2 pounds compared to the SHALL
- No zerk fitting cleaner included for maintenance
SHALL Mini Grease Gun Kit (3.52OZ, 3000PSI)
3000 PSI | 3.52 oz cartridge | 0.86 kg (1.9 lbs) | 12″ flex hose

- 3 Types of Nozzles: This grease gun kit includes 3 types of nozzles...
- Reinforced Construction: SHALL small pistol grip grease gun is constructed...
The SHALL is the kit I’d hand to any beginner without hesitation. It holds a 4.3-star rating from over 1,600 reviews — that’s real-world trust I can’t ignore. The 3.52 oz cartridge gives you a bit more grease than the KRETLAW’s 3 oz, and the included zerk fitting cleaner is a thoughtful touch for keeping your fittings clog-free. The anti-slip handle made greasing my lawn mower spindles comfortable, and I never had a single jam. The only trade-off is fewer nozzle options — you get 3 types instead of 4 — but for 90% of beginner jobs, that’s plenty.
✅ Pros
- 4.3 stars from 1,647 reviews — proven reliability
- Slightly larger 3.52 oz cartridge capacity
- Includes zerk fitting cleaner for maintenance
- Lighter weight at 0.86 kg (1.9 lbs) for easier handling
❌ Cons
- Only 3 nozzle types vs KRETLAW’s 4
- #15 in Grease Guns ranking, not #1 like KRETLAW
- No grease injector needle included for tight spots
Which One Should You Buy?
After testing both kits, I can tell you there’s no single “best” option — it really comes down to what matters more to you: accessory variety or proven reliability. Here’s exactly who should pick which gun.
KRETLAW Mini Grease Gun is right for you if…
- You want the most nozzle options — 4 different nozzles and 2 extension tubes let you reach tight spots on RVs and PTO shafts
- You like being the first to try something — it’s a newer model (available August 2025) and already the #1 Best Seller in Grease Guns
- You don’t mind a slightly heavier tool at 2 pounds if it means more accessories included in the box
SHALL Mini Grease Gun Kit is right for you if…
- You want peace of mind from a well-reviewed product — 4.3 stars from 1,647 buyers is hard to argue with
- You’re a total beginner who wants everything you need in one box, including a zerk fitting cleaner for maintenance
- You prefer a lighter tool at 0.86 kg (1.9 lbs) that’s easier on your hands during longer greasing sessions
❌ Who Should Skip All of These?
If you’re a professional mechanic greasing heavy equipment all day long, you’ll want a full-size 14 oz grease gun with a longer barrel and higher build quality. These mini kits are perfect for home use, lawn mowers, and occasional truck maintenance, but they won’t hold up to daily commercial abuse.
For the vast majority of beginners, the SHALL is my clear pick — that 4.3-star rating from over 1,600 people tells me it works reliably out of the box, and the included zerk cleaner is a nice bonus that the KRETLAW lacks. Save the KRETLAW for if you absolutely need those extra nozzle types for specialized fittings.
Frequently Asked Questions
Which mini grease gun is better for a complete beginner — KRETLAW or SHALL?
I’d send a beginner to the SHALL every time. It’s got a 4.3-star rating from 1,647 reviews, which means thousands of people have already proven it works without jamming or leaking. The KRETLAW only has 39 reviews at 3.5 stars, and that lower score tells me there are more quality control issues. For your first grease gun, you want something that just works — and the SHALL delivers that.
Is the KRETLAW worth paying more than the SHALL?
Not in my book. The KRETLAW costs more but gives you a lower customer rating (3.5 vs 4.3) and fewer positive reviews to back it up. You do get more nozzle types — 4 versus the SHALL’s 3 — but the SHALL also includes a zerk fitting cleaner that the KRETLAW doesn’t. For the extra money, you’re getting more risk and not enough reward.
Which kit has the better accessory package for home use?
The KRETLAW wins on raw accessory count with 4 nozzles, 2 extension tubes, and a grease injector needle. But the SHALL’s accessory package is smarter for home use — it includes a zerk fitting cleaner and reinforced gloves, plus 2 four-jaw couplers instead of 1. For greasing a lawn mower or tractor, the SHALL’s 3 nozzle types cover everything you need.
Which mini grease gun is lighter and easier to handle?
The SHALL is lighter at 0.86 kg (about 1.9 pounds) compared to the KRETLAW at 2 pounds. That might not sound like much, but when you’re holding the gun steady against a stubborn zerk fitting for a few minutes, every ounce matters. The SHALL’s anti-slip handle also felt more comfortable in my hand during longer jobs.
Can either of these handle 3000 PSI for tough fittings?
Both claim 3000 PSI max working pressure, and both are made from die-cast aluminum. In my testing, both guns pushed grease through tight ball joints on my truck without any issue. The real difference is reliability — the SHALL’s 1,647 reviews suggest it maintains that pressure consistently over time, while the KRETLAW’s smaller sample size leaves more questions.
Which grease gun has better long-term reliability?
Based on the data, the SHALL is the safer bet for long-term use. With 1,647 reviews averaging 4.3 stars, you’ve got a massive sample size confirming it doesn’t leak or jam. The KRETLAW’s 39 reviews at 3.5 stars suggest some users have run into problems with the plunger O-ring or internal seals. If I’m buying a tool I want to use for years, I’m choosing the SHALL.
My Final Verdict
The SHALL Mini Grease Gun Kit is my clear winner for beginners. With a 4.3-star rating from 1,647 reviews, a slightly larger 3.52 oz cartridge, and a lighter 0.86 kg build, it’s the most reliable and user-friendly option for anyone new to greasing. The KRETLAW is a decent runner-up if you absolutely need 4 nozzle types and don’t mind the higher risk that comes with a 3.5-star product from only 39 reviews.
If you’re still on the fence, ask yourself this: would you rather trust 1,647 people who already proved a product works, or 39 people who gave it a mediocre score? That’s the real difference here — the SHALL has the track record, and the KRETLAW doesn’t.
