I'll start with the issues with the guitar first. Mainly because there's only 1 sorta problem, and it's minor and doesn't really affect much. The rest are issues in the finish.
The bridge is a bit crooked, as seen in the first picture. The bass (low or thickest string) side is closer to the neck than the treble side, if it were the other way around I would of thought it was deliberate. The scale length is still 25.5 inches.
The finish is cloudy, over buffed and dimpled with a couple tool marks or scuffs on the back between the tremolo spring cover and the electronics cover, seen in the next 3 photos.
The action is quite high and it wasn't in tune. I haven't set it up yet so I don't know about the intonation.
When I received it (way earlier than quoted, 3 days), the box was in good condition. Inside the guitar was sealed in foam. Opened it up and immediately tested it out. I'm writing this review within 30 minutes of it's arrival. If something fails in the future, I will update the review.
All the electronics work. The pots do what you would expect. Tone knob has a minimal sweep, volume knob is kind of on/off. Not a surprise considering price point. The 5 way switch works as expected, is smooth, and doesn't make contact with the body on either side. The bridge is on par with price point and does the job.
The pick ups work as expected, under powered, but clear tone wise.
The fretboard is very dry, but that's easily fixed with some lemon oil. The fretboard edges are "rolled," definitely wasn't expecting that. The frets seem level, and polished, the ends aren't perfect, but won't tear up your hand. Fret inlays are straight and honestly nicer than I was expecting. The nut looks to be in order, and finished nicely.
Tuning machines are tight and smooth turning. It's holding tune so far. The strings will be replaced immediately, but again, get the job done.
The unfinished neck is done well, smooth and blemish free.
The accessories are cheap, but better than nothing. The 2 hex wrenches for the truss rod and bridge saddles will do what you need.
I am very pleased with my purchase, but the Chinese import business is a gamble and your experience may differ from mine. For the price, you can't expect too much. I happened to get a good one.
I wish I had this when I started playing, for the price it's worth having it set up by a pro.
:((UPDATE after playing for longer than 30 seconds)):
I replaced the strings with set of Ernie Ball, and that helped with some of the buzzes. The frets need a good polishing, quite "gritty," and need leveling, so the lowest action i could achieve was a hair over 2mm. Not bad for the price point. It ended up intonating just fine. Good luck on your purchase!

I've been a guitarist for a long time, I've owned many guitars that ranged from high-tier thousands of dollars expensive to some of the cheapest crap you'll ever see, so I wasn't expecting much from this modestly priced little axe, my first time owning a Glarry and I can honestly say that this guitar is fantastic, it sounded great right out of the box, the only set up it really needed was a slight truss rod adjustment and some light inotation, also it looks great, and it's light, it feels comfortable to hold and play...I recently changed the strings and it now sounds even better...great guitar for an affordable price, good for begginers and veterans

I had never heard of Glarry B4 I stumbled across this just browsing guitars. I had started a savings to purchase a second guitar and was really nervous about spending my savings on this. I expected to pay 4 or 5 times this cost. This guitar is absolutely amazing. It does take a lot to get it dialed in and I put new strings on it as soon as it arrived. After spending a couple of hours stretching new strings and getting em lowered enough without fret noise. The action on this guitar is awesome. This is quickly becoming my first or go to guitar. I will always check out Glarry guitars and for now at least I won't have to save nearly as long. That is until their quality is recognized and the price goes up to reflect it. Great guitar at all Amazing price. Highly recommend!!!

Good action. Smooth frets. 5 different pickup sounds available. Plus a whammy for less than a dinner at Fronos of Spain! Light weight, which many say is the trademark of a cheap guitar, but I love. It's as light as an acoustic! I hooked it to a vox amp and it sounded great. Noticeable tone changing. Smooth neck. Nice feel. Playability. Won't tire a student. Ease of use. Performance. A quality you won't find at guitar shops for this price. And it looks cool. Comes with a cord, strap, bag, tools even a pick, which I think was a nice touch.

There are a lot of things to like about this guitar and the first thing I am sure people will agree on is the price. Though you can find this exact same guitar for cheaper on Ebay (roughly 60-65). Though this is a Glarry guitar you may more than likely get the model without their branding on the headstock (the one from Ebay it seems) but it is still a fair price for everything you get. The gig bag included will have that famous plastic stench which goes away in a few days thankfully. the included accessories (strap, cable, pick etc...) aren't the highest quality but if you are a beginner they will definitely hold you over. The pick will warp/wear out very quickly though if you are an aggressive player. The guitar itself sounds great as-long as you keep it on either the bridge or bridge tones, the middle three options on the tone switch are just awful as they lower the overall volume of the output and introduce a ton of hissing. The strings that come with the guitar aren't amazing by any means but they are definitely usable. The main things wrong with the guitar I got that are true about most guitars is the setup. The action is pretty high and worse the nut was placed improperly and cut too deep for the strings it seems which could ruin the experience for new players but buying a new nut and getting a proper setup would easily fix this. The tuners are cheap as expected given the price so the tuning will almost never hold and when trying to tune it will skip around quite a bit. The fretboard I had gotten was very very dry and I have heard others with the same issue and its another issue that is easy to address but I figured was worth mentioning. The guitar did have some damage around where the body bolts to the neck which is disappointing but isn't too noticeable or problematic.

I would say if you are getting this for a young child/beginner its more than usable as is but you would want to get a proper setup if they do enjoy it. As for the rest of everyone, its definitely worth it even just to throw around and noodle some guitar riffs without having to worry about damaging a more expensive guitar.

Pros:
Price
Aesthetic/Style
Weighs very little (about 6 pounds)
Upgradability
Extras ( strap, pick gigbag, and cable while not best quality are very usable for a new player)
Size?(Can be a pro or con depending on personal preference. It is roughly 3ft long (about 37")

Cons:
Cheap hardware (tuners wont hold tune and are very jumpy)
Poorly setup from factory (nut wasn't set properly and just needs to be replaced)
Single coil pickup is useless as it lowers the output and increases static/noise
Dry fretboard
Body had chipped paint/cosmetic damage
