Well, the RockJam bundle is the one that shows up in every "best digital piano for kids" search, promising a full starter kit with a stand, bench, headphones, and app lessons. But after two years of teaching on a P-45 in my studio and watching my students' parents buy both of these routes, I can tell you the marketing is doing a lot of heavy lifting. The truth is that most of these bundles are built for the first six months, not the first six years.
I'm Yuki. I've been playing for 40 years, teaching for 25, and I've owned a dozen digital pianos. My labradoodle, Mochi, has slept through more bad renditions of "Für Elise" than any creature should endure.
I keep a postal scale in my studio to measure action weight, and I test every instrument with the same three pieces: Bach's Prelude in C, Chopin's Nocturne in E-flat, and a blues improvisation.
Here is the short list.

Every instrument gets the same treatment. I play Bach to test trills and clarity, Chopin for legato and sustain, and a blues improvisation for rhythm and dynamics. I also check the action weight with my postal scale and note how the keys feel after 30 students have played them in a week. I don't do unboxing content. I want to know what a piano feels like in month eight, not on day one.
The RockJam Problem
Let me start with the bad news. The RockJam RJ761 kit is the most popular kids' keyboard bundle on Amazon, and it has a real problem. One owner reported it "worked well for six months" and then turned off permanently. The manufacturer told them they hold no US stock and couldn't help. That's a ~$130 paperweight after half a year.
But the reviews are also full of delighted grandparents. One wrote about buying it for a 6-year-old granddaughter who "loves it." The stand is sturdy, the keys feel nice for what they are. The headphones are cheap and often arrive broken. The product images show a tablet that isn't included. That's misleading.
Here's the cost-per-day math. At ~$130, if it dies at six months, that's about 72 cents a day. If it lasts two years, it's 18 cents a day. The P-45 at ~$450, lasting four years, is 31 cents a day. The RockJam is cheaper per day if it survives, but the failure rate makes it a gamble. And for a kid who might actually practice, the non-weighted keys teach nothing about proper technique.
Yamaha P-45: The Real Answer
The Yamaha P-45 is the best value in the budget category, and it's not close. At around ~$450, you get a fully weighted action that Michael Mitchell, a 30-year pianist, described as "incredibly solid." The sound is good enough that one reviewer said you'd think you were playing "a reasonably high quality upright piano." That's remarkable at this price.
The version I own has been in my studio for three years now. Thirty students a week pound on it. Mochi has knocked into the stand more times than I can count. The humidity swings with the seasons. And it still plays.
The action is starting to show wear, which matches the four-year timeline that Weston N. documented in a review: the keys get mushy, clicking sounds develop.
That's the real review. This is a great starter instrument, not a lifetime purchase.
But for a kid serious enough to practice daily, it's the right call. It's 25 pounds, portable, and has a real action. The key degradation at year four is a concern, but by then you'll know if your kid is still playing. If they are, you'll upgrade to something in the ~$1,000 range. If they're not, you're out ~$450, not ~$1,500.
The P-71 Question
The Yamaha P-71 is essentially the same instrument sold through Amazon. Carrie Capell, a professional musician with 18 years of experience, chose it after "a significant amount of research." The complaints are minor: the sustain pedal is too light, the high-end octave sounds a bit thin, and there's no Hammond organ sound built in. These are not reasons to skip it.
Buy whichever is cheaper. They're the same piano.
The 37-Key Toys
Now let's talk about the cheaper options. The Kids Piano 37-key and the 32-key version are preschool toys. They're colorful, they're cheap, and they have volume control. For a 3-year-old who wants to bang on something, they're fine. But they have tiny, non-weighted keys and no real action. A child who learns on these will have to unlearn everything when they move to a real piano.
The STRICH 37-key mini grand is cuter. It looks like a little grand piano, which is fun. But it's still 37 keys, still non-weighted, still a toy. For a toddler who wants to pretend, it's great. For a 10-year-old who wants to learn, it's a dead end.
I don't track prices day to day, so I won't pretend to know next week's. But the pattern is consistent: these toys are built to a price, and they feel like it.
The RockJam RJ549
The RockJam RJ549 49-key sits in between. It's cheaper than the 61-key bundle at around ~$80, and it comes with note stickers. The keys are still not weighted, but they're a bit bigger than the 37-key toys. For a 6-year-old who wants to have fun, it's fine. For anyone who might actually practice for more than a year, spend the extra money on a P-45.
What I Tell Parents
Coming from years of teaching, I have a standard spiel. If your kid is under 8 and might not stick with it, buy the RockJam bundle. It's cheap, it's fun, and if it dies at six months, you're out ~$130, which is less than a month of lessons. If your kid is 8 or older and serious enough to practice daily, skip the toys and buy a P-45.
The best instrument is the one that gets played. A ~$200 keyboard with a broken headphone jack that your kid loves is better than a ~$6,000 slab that sits in the corner. But if your kid is serious, the RockJam's non-weighted keys will hold them back. The P-45's action will teach them proper technique. That's worth the extra ~$300.
The Acoustic Question
I own a used Yamaha U1 acoustic, and it's the best instrument I've ever had. The tone is bright and full, the key sensitivity lets you play "ppp notes all day long," and the difference from a cheap piano is like driving a 2007 Ford Focus and a 2013 Mercedes Benz C300.
But it's also a burden. Humidity requires constant maintenance, and if you live somewhere humid, you need a tuner to come more frequently.
For most families, a digital piano is the honest choice. No tuning, no humidity anxiety, and you can practice with headphones at midnight. The U1 is the gold standard, but it's also the most demanding one.
The Bottom Line
Here's what I tell every parent who asks. Buy the Yamaha P-45 if you want your kid to actually learn piano. It has a real weighted action, sounds like a real piano, and will last long enough to know if your kid is serious.
Buy the RockJam bundle if you're gambling on a 6-year-old's attention span. But don't pretend the toys are instruments.
They're not. And when the RockJam dies at month six, don't say I didn't warn you.
The P-45 is the best digital piano for kids because it's the cheapest instrument that actually teaches them something. Everything else is a toy.
