Question 1

Does this set come with two dumbbells, or just one dumbbell that weighs 40LB / 60LB?**

Accepted Answer

The set includes one single dumbbell. The "40LB" or "60LB" refers to the total weight of that one dumbbell (20LB or 30LB per side). If you need a pair, you'll need to purchase two sets. Many TikTok reviewers pointed out this confusion, so check your home gym needs before ordering.

Question 2

How secure is the weight locking system? Will the plates shift during use?**

Accepted Answer

The V2.0 uses a threaded locking screw and collar system. When tightened firmly, the plates stay in place for moderate lifting. However, some Reddit users report a slight wobble during fast or heavy movements, especially in barbell mode. For steady curls, shoulder presses, and rows, it works well. For snatches or overhead tosses, you might notice some rattle.

Question 3

Can I use the dumbbell in barbell mode for heavy squats or deadlifts?**

Accepted Answer

The barbell mode is designed for lighter compound exercises like bicep curls, overhead presses, and rows. The connection point is not intended for heavy squats or deadlifts. The maximum safe load in barbell mode is around 40-50% of the dumbbell's max rating. For heavy barbell work, consider a dedicated Olympic bar and plates.

Question 4

Is the V2.0 compatible with the V1.0 Northdeer dumbbell base or plates?**

Accepted Answer

Yes, the V2.0 is backward-compatible with V1.0 accessories. You can use V1.0 plates on the V2.0 handles, and vice versa. However, some users on YouTube note that the locking collars are slightly different shapes, so mixing and matching may require different placement. We recommend using the included collars for the best fit.

Question 5

What's the return and warranty policy if I receive a damaged unit or missing parts?**

Accepted Answer

Northdeer offers a 30-day money-back guarantee and a 1-year warranty against manufacturing defects. If you find missing collars, screws, or cosmetic damage, contact their support team with a photo of your receipt and the issue. Most buyers report a replacement shipped within 5-7 business days. For faster help, message them directly via Amazon or their website chat.
