- Are the 552 and 552i the same dumbbell?
- Yes. Both are dial-adjustable pairs running 5 to 52.5 lbs per hand and replacing 15 sets of weights. The 552i listing adds the free SelectTech app, which the 552 also works with.
- Which is cheaper right now?
- The 552i reached $350.00 on November 7, 2026. The 552 was $429.99 at playitagainsports.com on the same date. Check the current price before buying, since the 552i has moved between $350.00 and $429.99.
- Is 52.5 lbs per hand enough?
- For most home lifters, yes. It covers presses, rows, curls and lateral raises for a long time. Heavy squats, deadlifts and bench work will outgrow it, and those are better served by a barbell.
- Which lasts longer?
- They share the same metal plates and dial mechanism, so expect similar life. The dial is the weak point on both: set the dumbbells down gently and never drop them.
- Can I use them for a full workout?
- Yes. The 5 lb minimum works for warm-ups and small muscles, and 52.5 lbs handles most compound lifts. The length of the dumbbell gets in the way on close-grip moves like curls and overhead presses.
- Is the 552i worth the extra over a fixed set?
- At $350.00 it costs about what three or four pairs of fixed dumbbells run, and it replaces 15. You pay for that with bulk and a mechanism that needs care.
